93 sc300 low beam holder
 

would anyone happen to know if there is a replacement part for the retainer that holds the 9006 bulb to the housing (the part that the headlight twists into)? The bottom portion of mine seems to be missing. Also, would anyone know what could cause one low beam to turn on but not the other? The passenger side wasnt working, put in a new bulb and still nothing.

I don't see the parts in the diagram you are asking about

Would need a wiring diagram to figure out your low beam problem.

it seems to be a plastic ring that holds the tabs on the lightbulb into the projector housing. i believe it's a retainer ring but can't seem to find a replacement anywhere. there are 3 small screws that hold the retainer to the back of the projector. the retainer is what has the slots in it to twist the bulb in
