I just bought a set of Xenon 100W headlight bulbs on EBAY for $5.50 and the're for a 97-02 headlight for an expedition. will these fit on my 2001 f-150? thanks

 

They should.

 

will you post a link to the auction you got them at. That's a good deal.

 

Be careful high wattage bulbs have been know to melt wire harnesses. There are several options for upgrading. I have a few pix of my heavy duty harness in my gallery. I'm running Farenheit Xenons from www.xenonmods.com with a harness from www.suvlights.com

I'm sure someone will chime in with a silvania silverstar remark, and just my $.02... I tried them with a stock bulb, and a xenon bulb (all in the HD harness), and didn't care for them. They seemed very yellow compared to the Xenons... Maybe a little brighter than stock, but still yellow... I know most people here swear by them. I guess I just got a bad bulb. I didn't even bother opening the other one, just took them back...
