Home made "emergency lights
I'm a member of a Shriners riding unit that makes mini firetrucks and ambulances out of go-karts to ride in parades. Strictly for fun.
Many of the guys have spent hundreds of dollars to purchase "official" police vehicle lights but I'm thinking I'd rather tinker and make my own. I can probably do more with them this way then be limited to what I could buy commercially. I'd figure that I can get most of what I need in the way of LEDs and such through Radio Scrap or a local equivalent but I'm wondering if anyone knows of a site with some DIY plans on how to do this?
