Pretty common in dirt tracking. My '67 LeMans had early Camaro mono-leafs inside the rear fenders!

I'm not so sure. I rode shotgun on a friend's wrecker sometimes.

He pulled what I considered to be a completely disproportionate number of marked police cars, fire trucks, and school buses (which have strobe lights on on the back bumper here!) over the years. The drivers *always* said "but I didn't see it!", like it was some kind of get-out-of-jail-free mantra.

The street rod guys have the opposite problem; gawkers who are so intent on staring that they cross over into their lane, herding them off onto the shoulder or ditch.

Against the law in my state, and rightfully so. They're incredibly annoying. The oblivious cagers are a hazard; making them angry isn't going to help things.

I've been thinking of setting up a secondary brake light switch that would make the brakes only flash once the pedal is pressed hard.

Wouldn't help against normal traffic but if you really need to brake it would flash and alert drivers behind you.

I manually flash my brake lights whenever it might not be obvious to the person behind me why I'm stopping.

I have the "Back Off" brand third brake light flasher on my car. The third brake light is mounted on my roll bar. Works great. Russ

Just installed. Thought that I might need it someday.

In my experience the flashers do no good against the kind of drivers you're trying to alert. They're on their phone texting or watching videos, drunk, stoned, playing with the radio, or rummaging around on the floorboard like the woman who rear-ended my wife at 45mph a couple of years ago.

A friend pulled a lot of marked police cars, fire trucks, ambulances, and school buses that were hit by people who "didn't see" them, even when some of them had both lights and sirens going.

There is no solution that's guaranteed to work every tome, but incremental improvements help your odds, I think.

I do remember a trial of taxis in San Francisco 25-30 years ago where they had the warning light in the middle of the rear window like we have now, but it flashed quicker as more brake pressure was applied. I seem to remember they felt they were more effective than the ones that just light up with a constant brightness as we have in production cars now. I don't know why they were never brought into the Federal rules or production. Does anyone know why?

Cheers,

"Dizzy" Liz Dole left office!
I despise the Third Eye brake-light.
Too often blinding which is NOT good for following drivers night vision.

I think it was Joan Claybrook more than Elizabeth Dole. No one ever proved it was more effective, but they did come up with some clever statistics.

Traditionally there are strict regs as to how fast and how bright automotive bulbs can light up. That's probably what killed the variable brightness brake lamp. That, or a patent-troll (like so many other things).

Cheers.

The "research" consisted of adding parcel-shelf brake lights to fifteen marked Metro DC police cars. Over the course of the trial, which was less than a year, they still got rear-ended a couple of times. The "numbers", apparently pulled out of thin air since no control group was ever mentioned, said that it reduced incidents of rear-end collisions by 75%.

Now, figure out what kind of driver it will take to rear-end a marked police car in the first place...

As far as I know no real testing was ever done. It was just such an obviously great idea they signed it into law.

I wrote a number of letters back when word hit the magazines, and eventually got a "we don't care what you think" form letter.


Back when I used to meet up with guys from sportbikes.net for group rides, there would always be one or two bozos who showed up with those idiot taillight flashers. They always got sour when they had to ride at the back of the pack, behind the slowest bikes. And we turned away a few with the "headlight pulsers" because nobody wanted to have them flashing in their mirrors all day.

The setup I currently see on ambulances is where when they hit the brakes, the brake lights blink really fast for about half a second, then stay on. I liked it so much I have the same setup.
