Asking because while changing one of my bulbs I noticed that one of the covers between the bulb and glass had broken off at one of the 2 contact points :/
I'm not aware of a bulb shield inside the fog lamp housing like exists in the headlamp, but if it's a halogen bulb it's common to shield the front of the bulb to keep it from creating a halo or bright circle visible to oncoming traffic
Thanks for the response. There was definitely a shield on there between the bulb and the glass. I wasn't sure that if it was maybe for heat or something and got a little concerned but after thinking about it that seemed stupid.
The back reflective part of the fogs was badly peeling when I opened it up too. Any recommendations on a reflective paint or other product for the housings?
Might be best to replace the housing with either stock or aftermarket. I'm not sure a paint will last, but there is a chrome aerosol spray paint you can try, maybe it will last with proper prep.
EDIT: I believe in 99 Toyota went to a projector type fog. Maybe upgrade to those.
