the only difference between the chrome & plastic bumpers (as pertaining to fog lights) is the mount that the light housing bolts to. The mount for the chrome bumper looks like a teardrop, sorta. The other one is pretty much round. I've not seen a PN# for the mount by itself.From what I've read there's only certain ones that fit or work with the chrome bumper. 98% of what I've came across state "only painted bumpers" or "doesn't work with chrome bumper". The other 2% didn't specify. That's what's been so frustrating.
Maybe, but perusing Rockauto, the complete assembly bulb included aren't that expensive, about $45 per side for Chrome or painted.So if one has a broken foglight lens that is in a chrome bumper...could they use a foglight from a painted bumper by simply switching out any of the mounting parts?
