Here is a selection of lightbars from various kits. Also some random police car stuff. Some of them are resin. The last picture is just the resin bars. All were painted with Tamiya acrylics so you should be able to strip them.
Individually, I'm looking to trade for a "Thank You". If you want more than one I'm looking for older model magazines-Scale Auto, Model Cars, Fine scale Modeler, etc.
