Mach1 sport lamps: What do they do originally? in Electrical, Lighting & Electronics Posted Thursday at 11:49 PM Think they should be renamed Look Cool Lights. The real reason I'm replying ....need the correct bulb number or sometimes called trade name. I can't seem to find anybody that knows the answer. Maybe you could look at one of your bulbs and give me a reply back .......much appreciate your help going forward.
