Which bulbs can I use

I got a set of factory F-150 fog lights from a friend yesterday and the only bulbs I can seem to find are PIAA bulbs but I want some different ones. The number is 9140 but my question is, does the 9140 bulbs convert to a different number like 880,881,893?? Thanks

9145, 9155, 9005 according to what I've read are all interchangeable. Not sure about a 9140. Guess you'll have to take the bulb to the store & compare.
