Had some time to do a bit of checking.
Our trucks require a 9140 bulb for the fogs.
H10's are suitable replacements.
Per several sites: The H10/9145 is a single filament bulb, used as fog light bulb, same as 9140 and 9155, all have a PY20D base, the 9140 is between 37 - 40W and the 9155 is 55W.
Being LEDs, wattage draw and heat are not an issue.
So....since they all share the same connector and base, I say WTF?
