Sorry for this somewhat lame post but thought there might be some help out there. Need to replace the rear brake light bulbs and having trouble finding them in local auto stores. Tried Pep Boys, Advance Auto and local Napa stores and none could help. I can wait until Monday and go to the dealership but was hoping tomorrow I could find them somewhere local. Any help would be appreciated. The car is an '03C4S and I'm surprised these bulbs are that difficult to find...

 

Dealer? $10

 

Is this not a standard bulb? Go to napaparts.com. I just checked and they have them listed there.

 

Local napa store only sells Sylvania bulbs and had no listing on their computer for my car...go figure

Per owner's manual it's a BAY15D P21/5w bulb, US equivalent is Sylvania 1157 or 7528. Very common bulbs.
Available at regular auto parts stores.

 

I had my break lights go out, autozone & advanced auto both had them in stock. $6 usd I think. Also SUPPER Easy to change, just loosen the 10mm (if I'm remembering correctly) bolt in the middle of the housing (looking vertical, left and right of engine lid). Take bolt out, the housing has a clip; if you will, on the outside/other end of the housing in the fender, it comes out easy by sliding it out.
Remove the plug for electronics.
Clean the area under the housing (At least I did, it gets very dusty)
The bulbs twist in.

Reverse steps and test, shouldn't take more than 10 minutes to swap all the bulbs in the housing.

 

+1 on Pelican. These guys are great.
