Although some new technology may eventually make its way to brand new vehicles, there are literally millions of vehicles on the roads already that could take advantage of what I am calling a safer brake light bulb replacement.

This unit would look like standard units and would plug and play just like normal ordinary incandescent bulbs. However this bulb has an accelerometer and a low cost microcontroller on it.

If you brake your vehicle normal so it isn\'t a sudden stop (jamming on the brakes), the light bulb would just light up. However, if you make a hard stop, the accelerometer reports the excessive G-Force to the microcontroller and it lights up the bulb in a different way. Maybe it just lights it up much brighter, or maybe it flashes it in a strobe mode for 1 second before turning on steady at a bright level.

The reason for this is to let the driver behind you know that you have stopped hard and he can brake accordingly. This would allow for the prevention of rear end collisions and even if the collision could not be avoided completely, hopefully the person behind would be able to slow down and minimize the damage from the impact. We all know people don\'t always pay good attention and we have all seen cars hit in the back, that if the driver that hit in the back was warned somehow, maybe they could have avoided the problem!
