yes, but I thought the HID lights require relativly low amps once the arc is lit.

Think about it: The ESP duplicates a pretty big stomp on the brakes to 1 or
more wheels, doesn't it? That energy comes from, what, the ABS pump
electrically applying a brake? ...not your foot, obviously. That could be,
say, a 50-amp draw, which is like 25% of what it takes to start the engine,
which we know dims the lights!

Just a guess.
