Since the modulator is not officially installed on my bike I guess I should refrain from giving a rating. But I had to share my frustration with someone. I decided to have my local dealer install the modulators as I was getting ready to drop my 07 Gl1800 ABS of for a routine service and was going to pick it back up after returning from my vacation. The dealer called me before I left and told me the modulators were defective and I should contact the point of manufacture to get a new set. After contacting Kisan they told me they were sure the modulators were working properly as all units are extensively tested before being shipped (their words, not mine) and the possibility of a unit getting shipped and not working was highly unlikely. Kisan said to take the units back to the dealer and contact them while there if any problems occured again. (by the way the dealer had installed the day/night sensor earlier and I assumed they had kept the wire which runs from the master to the slave unit)..Anyway I returned to the dealer and the service tech (new service tech, the previous tech guy had quit) proceeded to tell me I had the wrong modulators so I had to go through the explanation that I had the correct modulators and that if he needed any help installing them to please contact Kisan. He did contact the Kisan for instructions for installation. After setting in their showroom for 4 hours the tech came out again and asked if I had the wire that connected the master to the slave unit. I told him the previous tech had already installed all the wiring and to check the bike again. He did and said the day/night sensor was installed but that was it. So I left the Honda dealership for the 2nd time without the modulators working and I've had to re-order the wiring that the dealership lost during my first visit. looks like it's going to take 3 trips to the local dealership along with ordering a few parts that were lost along the way to complete this process. ( I downloaded the installation instructions from the Kisan website and gave them to my dealer during my first visit. Guess what? They lost those as well!!

Another update from my previous review. Kisan had confrimed the existence of the problem. It can be called "2-second lock-out code" failure: "So, flicking the hi-beam on/off rapidly at night will cause the error code of 8 flashes." KisanTech.com really answered me on time. But, I don't know why, my GMAIL puts them in the "Spam" folder. I am sorry about that. Here is the answer from Kisan: "I discussed this with our software guys a few times but did not get a clear answer. It seems the '2 second lock-out' code is not fully implemented for all pathBlazer models across the board yet. This is due to the fact that different models go in to production at different times with different production runs. P115W-D is not scheduled for next production run till November 2008. The lock-out code will be implemented at that time. So, flicking the hi-beam on/off rapidly at night will cause the error code of 8 flashes." So, if you are in no hurry, wait until November 2008.

Update from my previous review. Good for the day riding but problem and even danger for night riding and terrible support. If you are riding at night, at least for my case, this modulator really has a problem with its "8-time flashes revert-back confirmation" of sensitivity adjustment. It means that whenever you intentionally or not flick you hi-beam light at ANY time of riding (not only first 2 seconds after the ignition is turned on as mentioned in the manual), the modulator "thinks" that you are trying to setup the sensitivity. For the reason that you are at night, the modulator will not accept the setting and give you back an "8 times hi-beam flashes" confirmation. AND, this 8 times flashes will ONLY terminated if you keep the hi-beam on and waiting it until all flashes are done completely, if you turn hi-beam off before, it will restart from zero next time when you turn it on again. This "extra-function" really bothers other drivers at night and you just lose your normal hi-beam functionality and it really distract your attention of riding which is quite danger. I have tried to make contact 3 times with Kisan (by sending message to www.kisantech.com) support but with no any answers from them. I am currently building a “by-pass” circuit to switch it off completely out at night and I hope it is going to work.

Update: I installed my modulator about 1.5 years ago and used to run them all of the time until I got stopped by the local deputy sheriff. He was quite upset with me. I showed him a copy of the law, but that didn't make it any easier for him to accept. He thought the law was dangerous as he said that drivers already ignored their lights and by adding these modulators to non law enforcement vehicles it would only make the matter worse. I felt bad for him. I do run them on rare occasions when I feel they are really necessary. They do work in getting others attention.

Excellent product and there is "no-documented" function that can be used in the night: quick click two times high beam switch, and now you can have a “self-flash” high beam light. It will self flash nine times and then stay on, if you turn it off and turn-on again before, it will remain 9-time flash. But this self-flash is slower than the day-light flash. Here is the procedure I used for GL1800 Airbag 2008 and I think it works for those “big-hand”: 1. Remove Ignition switch cover, 2. Remove Meter panel, 3. Remove Center Front Shelter, 4. Remove Fairing Molding (left and right), For right side high beam 5. Remove right upper panel switch, 6. Release two bolts of cruise actuator and release it, 7. Unplug cable and plug modulator master/slave and then plug cable again For left side high beam 8. Remove left fairing pocket, There is no way to reach the high beam plug for the foot warmer ventilation louver lever, so the best way to reach it is: 9. Remove left shelter inner cover: 9.1 - trim clip (flat head), 9.2 – 4 bolts of top left shelter, 9.3 – now you can reach the plug of left high beam, 10. Unplug and plug modulator master/slave same as right side 11. Connect the control wire to slave modulator, 12. Install cable between two modulators and sensor (I zip-tie it on the break cable) 13. Reinstall in the reverse order.

Excellent item to have. Super easy to install. Have to push hard and listen for the click sound indicating the clips have fully engaged the prongs of the bulb. As others have commented on, be prepared for vehicle drivers to react by slowing down or pulling off to the side. The latter always gives me chuckle. I have also had on-coming cars flash their high beams at me, and get this... when stopped at a light a few have let me know that my lights are flashing. If only they were that observant ALL the time. ;)

Well, I guess I am the only one with this problem, but I am having a problem getting the pathblazer unit to properly fit the prongs on the back of the bulbs. My right one keeps slipping off, especially when riding over bumps. They work fine, just don't fit good.

Update from previous review... They have been in place now for 3,600 miles and no movement off the headlight base... and the traffic definitely notices the bike now!

Put them on the bike last week... installation was a snap... took about 15 minutes, including the time to drill a small hole above the left fairing pocket to install the sensor. Good tight fit on the bulbs! The difference in traffic? Hey... meeting traffic, they pull to the outside instead of pulling toward us... Traffic entering the highway does a double-take, then brakes to let us by... haven't had any weird reactions from the folks directly in front, but we've only ridden about 400 miles with them operating...

Work as described, however, I am sooo tired of everyone slamming on the brakes in front of me. If they want to move out of my way, then fine. Anyone scared of modulating "White" lights behind them probably should not be on the road anyway. I sometimes find myself turning them off on two lane roads because of no place to pass or the "Scared" ones slowing to a crawl wondering if I am pulling "Them" over. It's bad enough when I'm at work and they don't pull over when I do turn on the "Red and Blue" strobes behind them. Overall...good and bad. Have to know when to use them and when to shut them down.

Don't care what brand of modulator a person uses but these are almost a must nowadays. I installed these while I was changing the air filter on my '06 wing. Made the job a lot easier while everything was down anyway. I've read some posts about them coming loose. My experience says that if you don't push them on ALL the way, they might come loose. Once they are all the way on though they aren't coming off without a lot of pull.

I've used Kisan modulators on three previous bikes and really notice the improvement in driver attentiveness. The goldwings have more powerful highbeams, so you might want to be a little more selective about when you use them. The 1800 has been the most difficult installation by far, mostly because even with the fairing pockets removed there are many obstacles to work around to plug the units in. Allow some extra time, but the result is very much worth it.

Well I have big hands and I used service manual to guide me thru installation. After removing everything but the tires I got the things installed. Not all that bad, not any worse then changing air filters. If you are not mechanically inclined have some one who is do this one. Love the product and what it dose to get the cell talkers to take notice.

This is the best product if you want to be seen, Had them on my 2004 and now my 2008. I can't even count the number of cagers I saw were about to roll thru the stop sign and stop abruptly. The weaving traffic stops over a 1/4 mile ahead, But, I've had trouble with the city police here in Miami/Coral Gables FL. they get all cocky when I hand them my laminated paper from the FDOT. I was warned that if a car pulls over and I pass them, I'm going to jail for inpersinating an officer I told him if he didn't like the law he was in the wrong profession. One time a MC police asked me to turn them off, I complied, but explained they are legal and he should check it out. Haven't had anymore problems with police for over a year now.

I posted a review in March of this year and just wanted to follow up. This device is the best safeguard for making sure you are seen by others. However, the reactions you receive from other drivers are mixed. While in Jackson, WY this past summer I was given the finger by a motorist. I have had people shake their fist at me and others quickly flash their lights as they approach. I can't tell you how motorists have pulled over or changed lines as I approach them. In late evening (just after the sun goes down) is when I get most people pulling off the side of the rode. I guess because the flashing becomes more pronounced. It makes me feel a little uncomfortable at times, but then I realize I am being seen.

These really get the attention of other drivers. The amount of light needed to make them operate is adjustable which is a nice touch. Be courteous with drivers on city streets. I've pulled up behind a few cars at stop lights and the people in the cars thought I was an LEO and would make gestures as if asking if they should pull over. Silly cagers.

These are a must have! Like many of the other reviews state, you need small hands to complete the install. I was able to do this job in about 30 minutes. I did make one slight error that increased the intsallation time, make sure to attach the connecting wire to the master, and feed it across before connecting the master unit to the bulb. It is difficult to do once attached. Guess you learn from your mistakes. These modulators sure do help to make other drivers see you, and it feels good when they give you the room on the road you deserve. It's like driving a bus instead of a motorbike. These get my five star rating as a must have safety accessory.

I had these installed by the dealer when I first purchased my wing. On the way home, I turned them on when approaching a truck which had pulled over to the side, leaving less than two full lanes with oncoming traffic. Like Tomcat, I was surprised when cars started pulling over for me, thinking I was an emergency vehicle. The powerful high beams on the wing make this modulator so effective that you have to be careful with it. I once turned them on when an oncoming driver pulled out to pass and I didn't think he had enough room. He sped up, but as he passed he motioned to me that my headlights nearly blinded him--in broad daylight. There was no doubt that he saw me and acted accordingly. It's great to have this available when you recognize a potential accident situation. I wouldn't be without it. But I wouldn't cruise with the modulator on as a rule. Save it for when you need it.

I had mine shop installed as I have rather large hands. On the way home (I-5 N to 91 W), I had them on for a test run, and for the 28+ mile ride I was seen by every vehicle that needed to see me. These are a very good safety item to have installed (should come standard). Along with the brake light modulator there is NO reason that you cannot be seen by other dirvers.

What appears to be an easy job turned out to be a 4 hour job. If you do not know how to do the job, the instructions won't help much. Once done they work great.
