I recently bought some H1 ST bulbs from Amazon after doing the product finder on the silverstar website telling me which bulb I need. It's fricken cold here in MN so I didn't put a ton of time into this but I pulled the existing bulb and cant figure how the hell this bulb is supposed to replace these. Anyone know how to put this bulb in there?

ps. I have a 2004 F150 Lariat Screw

 

I have a 2007 FX4 Screw...I believe you have the wrong bulb...
I just bought a set of H13ST for the headlights
and 9145st for the fogs...

here is a link to sylvania replacent guide

also they have a $5 mail in rebate per pair on the sylvania website

 

your link didn't work.....below is what I went by after I entered my vehicles info. I did buy the H13ST for my head lamps. I figured the 9145's were the std replacement halogens.

Fog/Driving light
9145
9145ST Silverstar High Performance Lighting: The Whiter and Brighter Halogen
H1
H1ST Silverstar High Performance Lighting: The Whiter and Brighter Halogen
H1XV XtraVision Halogen - The Brighter Light

 

Which bulbs are you trying to replace, the fogs ?

Not sure why Sylvania is listing the H1 bulb for the fog lamps, but that is incorrect.

The fog lamp bulbs are the 9145 bulbs, this is the same pinout as the 9140, which is the part number for the fog lamp bulb listed in the owners manual.

2004 is the only one that is listed incorrectly on the Sylvania site, the '05 & '06 MY show the correct bulb ( 9140 ).

9140 / 9145 bulb


H1 bulb

 

yep, thats them. looks like i have to return them and get the 9145's.....damnit!!!

thanks guys!
