tail lights problem help
Okay now the problems start about 1 month after, the left running light goes out. I tell the guy at the autoparts I think the bulbs defective he gives me a new one and tells me its my stereo system or I have a short or electrical problem. I told him probably not because I have had my stereo system for over 2 years and never had this problem, he said cars start doing these things when they get old. So I went home started taking out the thing that holds the bulbs, I left my light on while doing this and I noticed while I was taking it out it started flickering and working so I left every thing alone both running light work.
Now a couple of hours later the right side running light stops working, so I take a look to see whats happening its the same as the left I touch it it starts working but now the right side is dim and the other side bright and half hour later the right side just stopped working. So I just left everything alone and now I am thinking I got a electrical problem.
I was also thinking maybe these bulbs are just not working with the car I need mercedes brand. please help everybody I do a lot of night time driving and I havnt gotten pulled over yet please help

They are worth EVERY PENNY!

I had a similar issue so I purchased the LED about two years ago and never gave me a problem to this day. Installation is SUPER EASY: PLUG AND PLAY!
If you look at the socket, it's obvious it needs to be 180. You CAN get the offset bulbs to seat (not the right way), and they will light. The problem is, that the brake light and parking light contact are reversed, so your brights are on when your parking lights are on and your brake lights won't be bright enough. Sounds like this is what the original poster is experiencing.
I'm still looking for the proper bulbs, but I know which ones are the WRONG ones.

Stopped by NAPA, and they had 2 part numbers in their computer. One appeared to be the same bulbs with the offset nibs. The SECOND one had the nibs at 12 and 6. Those are the ones I needed. At NAPA, they stock Wagner lamps. Here are the 2 part numbers.
The ones with the 12 and 7 nibs: 17881
The ones I needed, with the 12/6 nibs: 17916
I don't know which models need the 12/7, but that seems to be the only thing the other stores stock. Napa had both, which is super cool. Less $ too. < $4. Their computers also have very good pics of the lamps, so the guy can show you exactly what the lamp looks like so you can double check. Easy to pull the lamps in the parking lot on these cars as well.
My car's a 2000 430 hardtop, and I needed the 12/6 lamps.
Hope this helps some folks out.

Great info. I thought i was going crazy when I went to auto-zone and the replacement bulbs the computer and book listed didn't properly work because of the little nibs were off place.
Crazy part is when I pulled the (what I thought) defective bulb out, the filament was not broken. Does that mean anything?
