Re: IML: '55 taillights- help needed



Jim,

How do you know the bulbs are fine? Remember, they are dual-filament bulbs,
like two bulbs living in the same glass house. One filament (the taller,
thinner one) is the dim taillamp, and the other (short, thicker one) is the
brighter brake/turn lamp.

Often if one fails, the common ground will employ the other one when both
are in use. Depends on how the car is wired.

Check these things:

Turn on the parking lights only. Do the taillamps turn on? Bright or dim?
Just for fun, check out the front parking lights too.

If the taillamps are on but too bright, turn the parking lights off, turn
the key to the last position before "start" (the normal running position)
and switch on one turn signal. Does it operate normally? How about in front?

Now, without turning anything off, turn the parking lights back on. Now what
happens, front and rear.

Now try the other turn signal, same routine. And then the brake lamps. And
while you're at it, with all lights off, have someone watch the front of the
car while you step on the brakes. Do the front turn signals erroneously
illuminate with the brakes? (This could indicate short or burned-out
condition in one rear bulb.)

Do you have spare bulbs on hand? (Is this a 6-volt or 12-volt car?) If so,
try replacing bulbs, even if they seem to be OK. Make sure they installed
correctly, not 180 degrees off (note the distance from the side posts to the
base of the bulb, and match it to the slots in the socket walls.)

If all else fails, post the answers to the above and we'll go from there.
(Dick B is at the So Cal Imperial picnic today, so the most brilliant
answers won't come until later!)

Hope this helps,
