The taillights on the Jaguar XKR-S have a reflection on the lens glass of a white light in random places. Also the reverse lights light up red.
The Oreca FLM09 has a green light that lights up when the brake lights come one, the green light should be permanently lit and not connected to the brakes.
The was one more that had the side markers light up under braking, but my mind is drawing a blank.
