Delta-V Lights

Smarter brake lights

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.

       This has been proposed in many different forms here, including the particular form you mention in your post. Why don't you try checking the appropriate categories next time? Welcome to the Halfbakery, but you're gonna have to try a little bit harder in future posts, ok?

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

       Welcome to the HB.
