My overhead console used to have that style bulb in it but I switched to a newer style that uses the 194 bulbs.

I know mine had a number on it but I don't remember the number. I do know that they were hard to find. Your best bet might be measuring it and comparing them to measurements online. I can look and see if i have the old bulb in the old console but it'll be Friday before I will be able to.

I personally would just replace them with some LED panels. Much brighter and will last a long time.

Yea it says 12v 10w on them. I think it was 10w anyway. Everything online is to long.
I'm considering leds, but I'm assuming I need to know the part number first so I can get the ones shaped like the stock bulbs. Not really in the mood for a retrofit with hot glue for some leds lol.

I looked for ones that were shaped like those and just like tha regular ones everything I found was either too short or too long.

Good luck with your hunt let us know what you find.

i managed to find out its a 39mm festoon. looking in autozone i found a bulb that was just a hair longer then the one in the ohc. its sylvania DE3175 LL. it fit right in its place. it was a little difficult to get the lock ring in to be able to turn and lock it. prob due to it being a hair longer, or cause i was looking up with my arms in the arm trying to change it lol

but it works. once again for anyone searching, Sylvania DE3175 LL.
