Ive got a 71 Duster and for some reason, the passenger side taillight bulbs burn out immediately. I pulled the first one which was black (and only about a year or two old) and replaced it with the same type bulb. When I tried the blinker on the drive home from the auto parts store, it still didnt work at all. I get home and look at the bulb to find the coil unattached from the piece of metal inside the bulb. The bulb was still clear. So I put in the 2nd bulb from the package and tested the turn signal. It worked but it was blinking way faster than the left signal. So I drive to work to find out that it went out again! I look at the bulb and the coil is unattached from the metal piece and the bulb was clear. I looked at the fuses and they are all good. Does anyone know what the problem may be? This just happened out of no where.

Problem is probably low-quality bulbs, even if they were bought under a major name. What brand did you buy?

The best-best-best bulbs you can install are # 3496, which are an ultrapremium bulb with extra-long life, extra-high output and it's got a corrosionproof nickel-plated base. Expensive, though.

Hey, Dan, since we got you on this thread and you're a top expert in automotive lighting and all (meant to convey the utmost sincerity ), I would like to ask you one of life's most vexing questions... If the bulb that goes out on an old car is an 1157, how come every glove box, cigar box, can full of old bulbs, parts car, shelf covered with bubble packs of new bulbs in the shed, garage, etc contains only 1156 bulbs, yet if the bulb that goes out is of the 1156 variety, all the available bulbs in a 1 mile radius (not counting those at the local Wal-mart) instantly change themselves into 1157 bulbs???! Doesn't matter how many times you replenish the depleted style bulb, either.

Asked and answered. That's one of the reasons why the expensive premium bulbs I mentioned previously work so well: The 6 and the 7 are reversed (3496 is the 2-filament bright/dim kind, and 3497 is the 1-filament bright-only kind), which screws up the Instantaneous Scarcity phenomenon you mention, formally known as the Doh Effect.

Hmmm, seems like I made a comment rather than searched for an answer way back when. I'm still looking for the answer, Dan!
