| I've got an old Olds that everytime I turn on the heater or defroster
the headlights pop. When I inspect the the lights or light (sometimes
its just one light) the bulb has literally popped. What the hell is
wrong with this car ? This is gettng expensive buying headlights.

Are the headlights turned on when this happens?
When you say "popped" do you mean the filament has burned out or the glass
has broken?

Are these Halogen type lamps or are they sealed beams?

The 9004 appears to be a Halogen lamp. Are you observing the stringent
handling requirements when you install a new lamp? My understanding is that
you cannot touch any part of the glass envelope while handling them, and you
cannot get let foreign material get on the glass while installing them.
According to a recent informative thread in the sci.electronic.repair news
group a higher OR lower voltage can be death to these bulbs also. How's
your alternator performing?

Yes, I'm aware handling them with care. And as far as I can tell the
altenator is okay. I've been wondering though, having looked at the
wires if the light sockets were the original sockets, if the 1st owner
wanting halogen lights replaced the old sockets with the older style of
bulb by cutting them out. This would explain the tape on all the wires
leading to the sockets. What do you think ? >> Stay informed about: 87'Olds headlights that pop. |

What kind of Oldsmobile do you have? I was guessing while researching the
issue, and assumed that it came from the factory equipped with Halogen
bulbs.
Taped connections? It might be good to take them all apart and inspect the
quality of the splices. Maybe the machine had an accident earlier and
someone put new fenders on it but did not rewire in a professional manner.
Is there any way that water could be splashing onto the bulbs through an
opening in the headlight housing?

Oops. I had forgotten that heater/defroster thing.
If low voltage really does zap Halogen bulbs then my suspicions would turn
toward a grounding problem. If the headlights and the heater/defroster are
sharing the same ground path for some reason such as a poor ground
connection for one circuit or the other, then that could reduce the voltage
applied to the bulbs even though alternator output is normal. Kind of a
stretch, but I'm running out of ideas.
