When you remove the bulb, there is a little black, plastic piece that the bulb plugs into that holds it in the socket. I broke it. Does anyone know where I might find another? Do I need to repair it, or can I just buy another?

This is NOT the plug/pigtail. That part is fine.

(Just in case) Before you decide to flame...I did search here and elsewhere and I cannot find the answer.

 

1st. Pics of that part help GREATLy.
2nd. Check the dealer, not only am I sure they can get you the part (might not be worth the cost), but if you bring donuts you might be able to get them to fix it for ya. Especially since you still have B2B.

 

If you cant buy the part take the one you busted and glue it up. Its there to keep water dust and stuff out.

 

My right headlight went out recently. Pulled it apart to find that not only was there no rubber seal on the back of the assembly, this little plug that much2saxy had problems with had melted at one of the terminals.
Did you ever find where to buy one saxy?

 

I believe you are looking for the H7 spacer. I would try calling your local dealership, those things are very hard to come by.

 

It doesn't help that there's no rx8s at any junkyard in utah either. I'll see what I can scrounge up from the dealer. Thanks for the name of the part paimon!

 

I did, in fact, find one. I just called the local dealership and paid about 10 bucks for it.
