Are you talking mounting radar "jammers" in the headlights? It won't do you any good when they aim the laser at you. You may as well just get a decent detector.
Strangely enough I have never gotten a ticket I didn't deserve, and I have deserved a lot more than I've got. That last part probably goes for EVRYBODY ELSE on this forum too. Even the LEO's!

No, I don't want to jam anyone. I'm opposed to jamming.
I just wonder if Yamaha could be less generous with the amount of perpendicular or parabollic focused surface out front. Within legal limits, of course.
Just a thought. Going now.... won't ask again..... sorry.....
We have a radar gun, and it was just a thought, mind you....

in the mid 80's one of the big car mags like hot rod or car craft did a whole article on reducing the radar signature of assorted cages. The conclusion was that it would be difficult to design a better radar reflector than a headlight. Cars such as a vette w/popup headlights had an instant benefit. The next big reflector was the radiator. Tilting it back was an instant reduction (like a vette) as was the use of a duct (like a vette) so that the radiator was not out in the view of the radar. If I recall correctly they were able to clock pickups about a 1/2 mile further than the vette. The motorcycle that they had was closer to the truck than the vette. So FJR with two big headlight reflectors and the straight up and down radiator should not fare very well. I also think that they had some success with screens of various sizes too.

Well, where is the spinoff of military technology when we need it?
not going to hold my breath for this one...

There is a product available (Lazer Veil) that coats the headlight lens to reduce lazer signature. That combined with a legal lazer jammer (not to be confused with any radar jammer which are illegal) and a lazer detector would go very far in avoiding LIDAR tickets.

First off, all of the following is IMHO. YMWV!
Keep in mind there are 2 issues here:
1- Laser. (uses IR light)
2- Radar (uses X, K, Ka band radio waves)
Laser
------
The vast majority of the return "signal" is generated by reflective surfaces (headlight reflectors, chrome bumpers, licence plates). With the FJR the only thing they are getting is the headlight. A product called "Veil" blocks the IR light frequency to cut down on laser return. Unfortunately "Veil" suffers from a few problems (From personal experience).
- Difficult to apply smoothly, ends up with a blotchy coating.
- Partially washes off in the first serious rain. (If your vehicle is a garage queen its probably not a problem for you)
- Blocks too much of the visible light coming out from the headlight. (Well, at least way more than I would have preferred).
If I were to try this approach again I would find a licence plate blocker for laser. Chop it into two plastic covers that I could attach to the headlight via velcro pads (or other quick release). Being premade it would avoid the blotchy and wash away problems. And when running at night could be easily removed.
Radar
------
Will reflect off anything metal, so engine, frame, etc. Headlight reflector is a much smaller percentage of the overall return. There is no readily available material for cutting down on radar return. That said, the earlier posting was right, the reflection from a bike (even the FJR) is _way_ smaller than for other cars.
Next time your out and see one of those "your speed is signs" play around a bit. Just before coming into range pass a slower car. Now maintain a quicker speed (15 mph). My personal experience is that you have to be damn near on top of the sign (couple hundred yards) before it picks up your speed and not the car way behind you (1/4-1/2 mile). Over the past couple years I've been paying attention to this and I am amazed just how much closer you need to be before the radar will pick you up and not the car way behind you. If its a transport truck behind you, he can be even further back. But the bleed through tends to occur around 200+ yards.
[SIZE=8pt](I am sure that when they started putting those "your speed is" signs that they realized there would be unintended consequences. I'm just not sure if they realized that one of them would be letting observant people "calibrate" just how far out their vehicles can be detected!)[/SIZE]
I pretty confident that with a good RD and provided you are not too far past the limit merely chopping the throttle (no brakes) is enough to bring your speed down (with no guilty looking nose dive) to a point you'll be ignored before he actually registers your speed. But of course if he's using instant on and your all alone on the road you will likely be nailed.
ECM (Electronic Counter Measures)
----------------------------------------
Detectors - Mostly legal, but check your local laws as it varies. Can detect laser and radar. V1's are the favorite. Personally I run the STi driver since it can not be detected by RDD's (spectre) which are used around here. (Google spectre to find out what I am talking about)
Laser Jamming - Mostly legal (again check local laws). Designed to give you enough time to knock your speed down before the gun "bleeds-through" and can pick you up. (IMHO) the problem is most units will cause the laser gun to generate an error code. Which the cop would see and now realize you are running a jammer. This implies guilty conceince so the cop would then pull you over anyways just to "have a chat".
Radar Jamming - I think illegal everywhere. There are passive and active which either dont work at all or really not very well. (See jamming link below)
Summary
-----------
Personal Opinions and Experience:
- I wouldn't run anything that might let the police know I am using countermeasures. I want him to think I'm just one of the masses that he doesn't need to pay attention to.
- If I block the headlight for IR, I want to be able to "unblock" during the night.
- Wasn't impressed with Veil, likely wont use it again (See above reasons)
- While not your original question, it always comes up: If you think having a detector is a licence to speed, then you are in for a very rude awakening. And why do I use a detector? Mainly when traveling out of home territory, acts as a constant reminder to watch my speed when in unfamiliar territory.
