No, can't run wig wags with HID. It takes them several seconds to
warm up, like sodium street lights.

Digging around the internet a while ago I came across the following:

Looks like wig-wag is now possible but at 4-digit prices.

The folks I've found who wig-wag HID's don't turn the lights off. They
simply cycle the lights from normal voltage to a lower voltage, creating a
wig-wag effect.
