Amber Lights Strobe When Braking
 

I recently saw a car with amber lights that strobed every time the brakes were pressed. It was just a fraction of a second, but it caught my attention for sure. I imagine it's a mod to decrease the chances of being rear-ended (with everyone on their cell phones it's much needed) but I'm just curious about the legality of it. Has anyone seen this done on other cars?

I made a GIF to demonstrate:

I always see the flashing third brake light but that's a new one.

I'm sure Diode Dynamics will have a kit for that soon lol.

Many vehicles flash the hazards under hard braking as an "emergency alert" to the vehicles behind them. This isn't new in that sense, though it is MUCH more common in European vehicles than in American vehicles.

Yup, that is a VAGCOM feature you can enable on USDM Audi’s/VWs.

I would be interested if this would be as simple as running a signal wire to the ABS sensor on our cars.

IIRC they also may have other not too common light functioning modes too .. imho it was some vw or skoda (also from that bunch/concern), where i seen light or left fog lights switching on separately during turns, probably to better illuminate roadside without resorting to fit some turning mechanism to main lights to follow steering wheel inputs ..
