Instead of lights that only activate when braking, a delta-v (difference in velocity) light activates in varying colors and intensities, indicating the level of vehicle acceleration or deceleration, deactivating all but a marker light when maintaining velocity, and flashing in the event of lost traction
or emergency braking.
For example, a 3 red LED marker light with three circles of LEDs around it, with the LEDs above it amber, and the LEDs below red. Slow acceleration/deceleration would activate the first half-circle of the appropriate colored LEDs, and color-blind individuals could identify them by their position (bottom=red=slowing).

I completely agree. It's something I've been thinking for a long time - "brake lights" should come on whenever a car is slowing down, not just when the driver is braking. Because some people have terrible depth perception :) |

Part of this is baked though, the Mercedes Pre-Safe system flashes the lights during emergency braking. |

Just you ignore [21_Quest], [meshaneian], it can be a bit grouchy at times. |

The "Emergency Braking Alert" warning system was demonstrated in '82 on Tomorrow's World - the system they demo'd was developed by Lucas. and the demo vehicle was a Jaguar V12. Seemed a really excellent idea, buy like all good ideas it never was developed further. I put a similar (though DIY - version) in the Dutton kit car I helped build in 1984 - in case of a frontal impact, the rear fog lights would flash in an alternate pattern - i.e. "STOP" warning to following traffic. Never got to test the system out in real life though (fortunately) |

Nevertheless a very good idea, and so what if it's been mentioned before - ofthen the nest ideas just have to be repeated until people start to really take note! |
