#CHMSL

I’ve noticed various new-ish cars, ranging from Kias to Lincolns, with a flash-then-steady mode on their center high-mount stop lights. Is this becoming standard? I expect it’s not federally mandated, but I can’t imagine where else it’s coming from.

More importantly, how is it being implemented? I’m thinking about grabbing one from a salvage yard in a few years.

Sajeev,

I was looking at a new Fusion in the company parking lot and noticed how its center brake light (CHMSL) is basically a very thin flap jutting out of the top of the window. Subtle… The center brake light is always like this. We are right now in a golden age of headlight and tail light design. The complex shapes and chrome and LED’s and rocket thrusters dominate the style of a car. But the center light gets none of this.
