I had wig wags in my crx, it was pretty fun. Took about 25 minutes to install if that. It just spliced into your high beam wire on the right side pretty much. Had a number of patterns. If I ever do a flush mount setup I'll probably get em again. Actually.. Maybe I still have that somewhere.. dunno it was kinda car specific.
Steetglow, liteglow, and others make strobe kits. For wig wags check out
www.galls.com but i think you need a connection w/law enforcement (my friend has an account from when he worked with the local pd) to buy anything though
