Review on 🔌 H7 LED Headlight Bulb Holder Adapter for Mazda 3/5/6 M3/M5/M6 - TOMALL by Joshua Mejia

I wanted to get rid of my horrible halogen bulbs but they came with a black gasket which made it impossible to install an LED as the metal retaining ring presses against that black space and holds the bulb in place. The black seal addon is great and works as intended. Only the driver's side headlight requires more force to press the ring against it. This spacer is thinner on the sides so you need to be extra careful where the ring rests on it. No problem for the passenger side. Remember that you cannot use rubber dust caps. Must buy on the secondary market. I used an inverted one to allow the fan to stick out and let the LED run at operating temperatures. A good buy! It didn't need to be sanded or anything like that. Racks or sticks are a little smaller than OEM, but it doesn't hurt the installation.
