Will these bulbs fit the dim headlights of the Raxiom Chrome Projector Headlights? .I just had the Raxiom Chrome Projector Headlights put into my car. They look AMAZING! But the problem is the dim lights. They seem like they are pointed down and I can’t really see far. I am wondering if I replace the Raxoin dim lights with the Sylvania if it improves my visibility and take away of the "pointed down" headlights.


  • The Raxiom Chrome Projectors for the 94-98 Mustangs take a 9005 series bulb, not these 9004 series. I've attached the link of the correct bulbs below for you. As for the pointing down, you have to aim the lights in order to correct that. Hope this helps!
