Im fixing to order these headlight houseings off ebay and I was wondering what Sylvania SilverStar ULTRA Headlight Bulbs do i need to fit in them? The 9007(HB5)? The truck is a 2003 F150 xlt fx4. Here are the houseings if that helps.

I came here to soley complain about the ultras...

If you are disappointed in Sylvania Silverstar Ultras like I was because they only last under a year, get the SOLUX bulbs. They're a noticable improvement in brightness and a fair amount whiter than OEM (similar to the ultras), but they don't burn out real fast. Their claim is they last as long as standard OEM bulbs. At $50 a set for ultras, I wish I would have realized that the ultras burn out so fast. The solux are about the same price, but (according to solux) they last up to 4x longer than ultras. Oh, and they're not illegal and they're not obnoxious/blinding...just better lighting.

 

I can't recall the last time my ultra's burnt out in my Ford but they were at least 2 years when I sold it. The one's in my wifes SUV have been in there for almost 3 years. You can also get them on ebay for about 30 bucks a pair, sometimes less. I've had them in my new truck for 8 months, no issues yet.

 

The answer is none of them. The Silverstar is a dim bulb designed to look bright. What you need is a brighter bulb. The Sylvania Xtravision is a much brighter bulb, helps you see better, they last longer, they produce less glare. They are also cheaper.
