The bright lights alternate flash on and off. A lot of Police cars have wig-wag bright lights, show cars, parade vehicles, etc. Im not talking about strobe lights, this is when the cars Hi-beam takes turns flashing.

Crazy name but that's what they are called.

Google Wig Wag Flashers, tons of info. I use them to get slow movers out of the fast lane on the highway. They work extremely better the just hitting the bright lights.

Thanks I made the order.
