How much does it cost to change a light bulb?

But I read about some new cars that put the Hazard warning lights on automatically if you're braking very hard, surely that is better than extra brake lights or multi-part lights. Problem is, in the dark you'd never be able to tell if the entire brake light is lit up, or if just a portion of it is lit. Also, with the vast age span of cars on the roads, some cars brake lights are brighter than others, so you'd never know whether the bright brake lights are for hard braking, or just a fairly new car. Same goes for dim brake lights, is the car old, or is the guy just braking gently? I think the hazard warning system would be the best.

this system provided fast flashing cyclops brake light for heavy braking so same idea really. Has just got to be a good idea especially on ****** chelsea tractors & Vans where you can't see what's going on in front.

With an auto you can sit with your foot on the brake all day so brake lights on without actually braking. Not good really

not in the Audi you can't. If it detects both pedals are depressed /ubbthreads/images/graemlins/frown.gif for more than ten seconds it drops the power.
