how are the headlights SUPPOSED to come on?

MarkRHayes · 08-03-2006

the 72 opel gt i got was rigged to turn on the headlights by a toggle switch mounted on the left side of the dash board. it works fine but i'd like to get it to work like it was originally meant to be. are the lights supposed to come on as soon as the headlight lever is pushed forward? i had heard that there may be a switch directly behind the left headlight and a switch connected to the headlight lever. how do i figure this out?

Yes the headlights are supposed to come on when the headlights are rolled over. The GT I bought had a toggle switch too. I just replaced the headlight relay and everything was back to normal. There are several threads on headlights and the wiring. I used the wiring information from these threads to check out the circuits and verified that it was the relay that was bad.

Mark, on Willit?, my 72 GT, there are 3 microswitches. 2 in the driver's side rotating mechanism and 1 on the passenger side. Only one on the driver's side powers the headlight relay. The other 2 are for an unlock indication in the instrument panel light cluster between the tach and speedo. There is no switch on the headlight lever. There is an excellant tech article by Wayne Torman on the OANA website for disassembling the headlights and accessing the rotating mechanisms. Also Keith Wilford on this site has done an excellant thread on repairing the rotators. In that thread I have a post showing the microswtches and the color coded connections to the microswitches. If you wish to make your headlights like original, I will advise you it is NOT a weekend job. I would suggest you download Wayne's article for disassembly of the headlights and buckets, then read Keith's thread on the rotators. HTH.

To add to GtJims response, get a service manual for your year car and when they come up, Destecs electrial schematic. Books for cars.com sometimes carries manuals, and they come up on Ebay as well. Happy reading, there's a LOT!

As Maynard would say, "You Rang!"

You can contact me directly if you need one.
Have 6 posters ready to roll, and Rev M is available (made the ignition switch larger and easier to read, as it is the heart of the car, and separated off the turn signal switch-euro parking light switch to show that is separate from the ign switch--creeping embellishments, I call them. And Rev L and M show the windshield wiper switch 'schematically.' yada...yada...yada...
