If you still have your stock headlights, try the bulb in your projecter headlight. If they fit then order the new bulbs. If they dont fit, well at least you'll know before you order.

 

I think a bunch of us did, myself included. They're on and look sweet. ProStreetLighting is probably like WTF? where are all these f-150 owners comng from.

 

ok these bulbs are the same bulbs as stock so of course they will fit the projectors...also i did have these on my truck but one bulb burnt out...so i went home an put the stockers back in, and i was super surprised to find out how dim these silver ones where compared to stock, i guess the tinting on them really dims out the light, that is the only downfall i found, other then it burning out in only a few months...hope i answered some questions

 

Finally, that doesn't suprise me. I did something like those in my last car except they were blue. They didn't shine as bright and only lasted a few months. I was even extra causious as to not touch them.
