This is generally a corrosion problem. What will happen is the corrosion will build up and provide enough electrical resistance to block electricity from flowing from the bulb. Remove the bulb and look in the hole. You should see two flat brass tabs (springs) that the two nipples at the base of the bulb rest upon. If you just see one or one and a half, go buy a new housing. Otherwise scrape the corrosion off with a small flat-tipped screwdriver. There is no need to remove anything, but if you do have the housing off the car it is easier to perform this procedure. If you can try to bend the spring towards you by using the screwdriver blade. Just bend it a smidgen (a smidgen in this case is 1mm-3mm ;). Now take a wire brush and buff all of the metal on the light bulb and housing socket. We want to get all of the corrosion off now. There is no need to scrub the nipples as they are a soft metal and shine easily (okay, dudes, no comments here! :) *Lightly* coat the springs and the metal of the bulb with either some kind of oil like WD-40 or use electrician's grease. This will help keep the metal from further corrosion. Reinstallation is sorta touchy at this point in time to get everything lined up properly. Install the bulb and turn on your parking lights and your turn signals (or emergency flashers). Put on a pair of sunglasses and carefully rotate the bulb a little left or a little right because chances are good that only one of the elements are lit. Be careful since the bulb can get hot (lucky? for you Seattle is getting the same weather as Portland is so the hot bulb will probably feel good!) As soon as you see both elements light up properly you can turn everything off and lock in the lens. Yer done!

The turn signal light doubles as a marker light and this function works. I checked the bulb and it's fine. But it does not flash when the turn signal is activated. When I activate the turn signal, the flasher blinks at a faster rate than the right signal lamp. What should I check?
