    I have smoke head lights and want to know if i buy 9004 sylvania will it help with visibility 1992 mustang GT

    • The Sylvania Silverstar Ultra Light Bulbs are brighter than the factory bulbs, and they will help increase visibility when compared to the stock bulbs.

    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!

      Great Bulbs, they provide a great amount of light

      It's hard to tell if they really light brighter than my old bulbs because when I upgraded I also installed new headlights, from what I can see on the road the light that they emit it is very white unlike how my old ones lit, which were very yellow and hard to see. Now I can see at night well and love it!

      Clear above average bulbs!

      I really liked this product! My head lights came stock with bulbs and I ended up replacing them for these anyways! Got rid of the blue stock bulbs that came with the headlights and threw these in! Not only were they not blue, which is exactly what I was looking for, but I was surprised to see the difference in how much more they illuminate on the road! Definitely recommended worthy the $40 or $50 for sure!

      Totally Worth It!

      These bulbs are the best out! I have them on my 91 Mustang GT and I get comments all the time about how bright my headlights are. These headlight bulbs are SO bright that I once got pulled over because the police officer said I was blinding him from the back and that he thought I had my brights on. I quickly reassured him the bulbs I was running and was let off with the cop looking stupid. Love the way my headlights look and I feel safer driving in the dark than I ever did before!

      Sylvania Silverstar Ultras

      These bulbs were a great addition to night driving, adding greatly to visibility range and brightness. I'd strongly recommend this small, inexpensive, easy change to any car.

      Simple, Easy, Effective

      These were fantastic lights compared to the ones I had in the car. I drove down an unlit country road everyday to work so these are greatly appreciated and were a very much needed improvement.

      Turns the night into day!

      These bulbs are great! A must, especially if you have smoked headlights or live in a rural area, with no street lighting and lots of wildlife. Big improvement over standard bulbs. Just make sure your headlight aim adjustment is correct and remember to hit the low-beams for oncoming traffic.
