I put on my ’06 Mustang. When I first installed it, it worked fine. Then I turned off the vehicle and turned it back on,and it stopped working. So I took it back and got another one and it did the same thing again. The passenger side works just fine, but the driver side won’t. When I put the factory bulbs back in they both work just fine. I compared both of the halogen bulbs and it doesnt seem to blown. Your help is greatly appreciated thanks.
