This is my 2nd Hyundai. I've had this car for two weeks now. The passenger side rear far right brake/parking light is only operating as a brake light. After a parts supply store informed me very incorrectly that the entire fixture needed replacement. I took it into Hyundai and was informed it was just a bulb. I attempted replacing with the 2357 Sylvania, and it works as I'm pressing it in, but will not twist into place to complete install. Any suggestions? I'd greatly appreciate any advice.

 

That bulb has two nipples. One on each side of cylinder part of the bulb.
One is higher and one is lower
You need to look at the socket and bulb and match the correct nipple to the correct slot for twisting the bulb into place.

It should be a double filament bulb
And meant to go in one way only

 

I'll try it again🤗
