I tried to order some replacements and was unable to confirm what the bulbs are for the cab of an 07 dually and the replacement bulbs for the dually fenders.
Not the recons...just the replacements for the factory bulbs.

I think they are all 194's but need confirmation please.

Thanks

 

That's what they are #194.I call them "the flash bulb lights"(if your an old guy like me)
I went out to my truck to check to be sure.Good luck.
