So what's distinguishes a "crutch" from a "good thing"? Just the aiming?

I know you don't care, but isn't modulating the high beam illegal except for emergency vehicles?

No. 50 state legal

It is a good thing if it helps others see you without negative affects.

It is a crutch when it is done to force others to pay more attention to you so you don't have to pay more attention to them.

No. Per federal law, it's legal in all 50 states.

I get them from this guy: (not affiliated except as a customer)

http://www.ebay.com/itm/CATZ-FET-XLO...ht_19206wt_991

He used to have a surplus of them and sell them for $90/pair but raised his prices about a year ago.

I run them on ALL of my bikes and swear up and down by them and, though I don't take it for granted, they really do radically increase the bike's conspicuity in traffic. The first time I saw them in person on a riding buddy's bike I just HAD to have them.

The one caveat if that they're 70W each so you need to be sure you've got enough extra alternator output to run them.


Side note: I sure wish somebody would have the good sense to come out with some nice amber LEDs.

So why is it that the majority of bikes I see with modulators are nearly the size of a small car (Goldwings)?

Now, see... THIS is exactly why we need MORE government...


We'll need an office plaza to house the new branch, and maybe even an ENTIRE fleet of cycle checkers, each one complete with his/her own Toyota Prius so we don't hurt the environment...

S7.9.4.1 A headlamp on a motorcycle may be wired to modulate either the upper beam or the lower beam from its maximum intensity to a lesser intensity, provided that:

(a) The rate of modulation shall be 240 40 cycles per minute.

(b) The headlamp shall be operated at maximum power for 50 to 70 percent of each cycle.

(c) The lowest intensity at any test point shall be not less than 17 percent of the maximum intensity measured at the same point.

(d) The modulator switch shall be wired in the power lead of the beam filament being modulated and not in the ground side of the circuit.

Whelen Engineering has a line of Super LED lightheads that are reportedly very bright:

I wonder how many lumens those put out. Whelen doesn't seem to have any tech info on their site.

I really like the modulated tail lights. They flicker fast enough to make it obvious that the rider is not "brake checking", so nobody is annoyed. Standard LED tail lights actually modulate on their own, but it is faster than the human eye can detect (consciously), but the eye is still drawn to them.

I would not personally want to run the modulated headlight, though. Like the story in the original post, I think you risk causing a traffic hazard you will have to navigate. Even if a crash is caused by confusion or stupidity, it is still a crash. Small amber LED lights would do the trick.

Having a bike and gear that isn't the same color as the road also helps. The other day, I saw a rider on a grey bike, wearing all grey gear. It was raining, and I barely noticed him/her. On the flip side, I followed a guy at night who was wearing gear that was completely outined in reflective pin striping. It literally looked like it was electrically powered!

Seems like where you can really run into an issue, is at night, when a single headlight offers very little help to depth perception. The "triangle of light" or whatever you guys call it helps you judge the oncoming riders distance and speed much better. Having amber or orange colored ones seems to help even more, they don't blend together as much.

As far as modulators go, I wouldn't run one, i find them irritating. But if it helps you be seen, go for it. If a driver is too fucking stupid to tell the difference between a headlight and a lightbar from an emergency vehicle, then they shouldn't be behind the wheel.

Strobing high beam HID lights in my mirror or way off in the distance up ahead always succeeds to get my attention long before I see the blue light. And the red light isn't visible until a fair while after I see the blue ones (or maybe it's the other way around?).

I have also been pulled over by an unmarked traffic patrol car which did not have any blue/red lights, he just flashed his headlights at me (which I assumed was road rage, and presented my middle finger... lucky he took that the right way ). He followed me for quite a while, at the speed limit, until I finally turned off at an intersection where he cut me off and thrust his badge out the window.

Flashing headlights should be used for actual communication only.

IMO a set-up like Duck is about as good as you can get and more effective than a modulator. Couple the triangle with the low horizontal and a lane weave and you are not going to get much better.

Of course one should always ride in such a way as to avoid anything that comes lights or no.

It's different here, and legal. Re the unmarked car, that doesn't necessarily go here. We had one incident where someone pulled a doctor's car over using a private guard badge and proceeded to shoot and rob him. We have official unmarked cars, but they have concealed lights and siren, and they use them. I personally won't stop for someone in an unmarked car who flashes his headlights and a badge, especially at night. I'll pull into a well lighted gas station while calling 911.
