Friend says "Jim, Your left brake light is out........" Sure enough......and last week I had replaced the center section bulbs in the STS, disregarded my own advice, and blew off the outer bulb set (brake/running/turn).

Soooooooo.......pulled it apart a couple of hours ago - simple for the outside assemblies - and cleaned the assemblies and body area and replaced all 4 of the #3157 bulbs. Piece of cake.

Heads up: These bulbs were 7 years old, and the inside of the brake bulbs looked like a silver flash bulb - almost completely coated with filament burn. The car has exactly 50,000 miles on it, so there hasn't been a lot of constant brake light ON time.......YOU may be due for some spring bulb work...........

Got bored, so pulled the old OEM bulbs out of the trash bag in the garage. None of the bulbs shown has much life left........even the relatively clear set of 3157's at the bottom have distorted, black filaments. 7 years old.

BTW, the inner pair of red lens bulbs in the license plate/taillight section are the old bayonet style 1157's, NOT the newer 3157's. Be prepared.....

When you're looking at these dual filament plastic wedge base bulbs, #3057 is the OEM wattage, #3157 is a tad brighter on the low (running light) filament, and #3457 is a tad brighter on both filaments. #3457 makes a good backup light because the high filament is quite a bit brighter than the 3057. It doesn't matter that they are dual filament: the sockets are already set up to light the proper filament.
