Ceiling lights into sequenced wig-wag flashing strobes?

You would need:

4 lights on separate circuits.

A 4-channel chase light controller.

You would plug each of the lights into its own circuit on the controller, then plug in the controller. It will sequence each of the lights in turn. Most controllers allow you to set the speed with which the lights chase, and some controllers offer different functions such as a build, fade in, fade out, etc.

Controllers can vary in price from very cheap to rather expensive DJ equipment. I'd suggest shopping on Ebay for a chase light controller in your price range.

all you desire is a familiar container that wires on on your extreme beams. it particularly is not puzzling and may be put in very particularly in an hour. many volunteer fire adult adult males as properly as shape workers use those as properly as police and fire. as long as you do not alter them with blue or pink lighting fixtures fixtures(in specific situations green unlawful)they're criminal. examine interior of sight ordinance out of your area. i'm curious why you desire them. females,by no capacity cease for in simple terms flashing headlights. a lot of weirdos accessible.
