Nice idea. I’m in the habit of watching for wheels to start rolling when I’m worried someone will unexpectedly pull out in front of me. A brake light is easier

Nice idea. I’m in the habit of watching for wheels to start rolling when I’m worried someone will unexpectedly pull out in front of me. A brake light is easier to see. Another scenario is an oncoming car braking which could help notice an animal entering the road or that the car has lost control ahead of you (sudden ice, for example.) Why green instead of red? Would it be an inverse brake light (green appears when foot lets off the brake?) I don’t see how any color light is easy to retrofit. > The innovative design of front brake lights adds another layer of practicality. These lights would emit a green glow rather than the traditional red, easily integrating into current vehicle frameworks without extensive modifications.

I like the idea of all-around-visible brake lights, but also think they should be red only. The problem with green on the front is that cars stopped at a light at night will be presenting a green light to oncoming traffic that should also be stopping, possibly overriding the red traffic light or stop sign.

  Green is also the only color, to my knowledge, that isn't commonly restricted for accessory lighting. The laws governing strobes and sirens are written broadly enough that they cover any light that you could possibly make blink, even if you don't do o. In most US states blue is for police and red is for fire. Some states let other vehicles, like tow trucks, use blue. Sometimes they'll use blue and red for police - but blue is always restricted to my knowledge. Yellow/Orange/Amber is for "caution". Some states restrict that and some don't, but it has an understood meaning. Purple signifies a hearse or funeral procession. I learned about these laws in the early 2000s, when I was in my late teens and early twenties and wanting to drive a customize minitruck. It turned out that in my state, all colors of strobes and accessory underlighting were restricted... except green. What's worse is that the law specifically includes a provision where possession is considered to be sufficient evidence of use. Technically it's illegal to buy a battery-powered toy with an LED strobe in it, if you drive home with it within reach of the driver.

> I’m in the habit of watching for wheels to start rolling when I’m worried someone will unexpectedly pull out in front of me. A trick I learned years ago from a motorcyclist: pay attention to the front wheels of cars near you in traffic. Very often, the front wheel turning is the first noticeable visual indication that a car is changing lanes or turning. That gives you a few more fractions of a second in a situation where they could be very important. After a while, I noticed that I was instinctually able to tell more accurately if a car is accelerating or decelerating. After considering it, I realized that I actually could tell better than before, but it wasn't instinct. Because I was watching cars' front wheel, I was able to see the front suspension load and unload as they accelerated or braked respectively. It was just subconscious.

  I like that idea; thanks.
