no man i didn't cut anything on the headlights i'm talking about the little black sockets that hold your factory bulb. well extec comes with special adapters for the mazda 3 and other kits don't so instead of using rubber washers like everyone is doing on the other forum, I took the stock bulb socket then cut the back of it off and remove the two gold female connectors from the inside iof it. therefore i have custom adapters. I'll try to get a picture up when i have a chance if you don't understand. but no i didnt cut anything on the headlight, and the bulb sockets are only 11 bucks a piece so if i ever need new ones there no that much.
