I am just using factory out of cars , I don't think they should be trouble .

Continuing to sweat out my wiring, my five year old grand daughter sat in my car and played with the knobs and lo and behold the parking lights finally came on. However I cannot do it again! Does anybody recommend a better light switch than the present Speedway part No. 910-64051? I ordered another one on the chance that the first one is defective. What are you using IC2?

Most of the switches commonly used in rods are GM based. You should be able to run down to any local parts house and match up a switch with your original.

IC2 has taken a hiatus and probably won't answer soon.

I have a GM switch, but the thing that bothers me is that the running lights stay on with the headlights and since there is no seperation b/w the headlights and running lights in the bucket they bleed together. I bought a secondary switch to turn off the running lights unless I flip that switch first. Hopefully that will work for me, but have you guys run into this with a factory GM switch?

I got my headlight switch from Ron Francis as part of the wiring kit. It turns off the front running lights when the headlights are on. ( I'm pretty sure it does anyway! ) and I have noticed that some switches do keep the running lights on with the headlights, and others do not. But I'm not sure if it's "manufacturer" specific or model specific?.?.?

If interested, I can see if I can find a part number.. on a side note, this switch has a crappy dash light dimmer control.. really only has 1 position where the gauges are lit.

If the running lights don't stay on with the headlights on I would be interested to know the part number. I didn't even think that maybe some switches would operate differently. I have a bit of time in modifying the switch to mount in the dash the way I want, but that is just the outer housing so I could still swap that over to a different model.

OK, I don't anticipate getting to the shop 'til tomorrow evening. I'll verify the switch operation and if it is as I think it is.. I'll look through the paper work and get the number for you.

Gm and Gmc headlight switch prior to 1966 trucks are all non power to the running lights, most owners that buy these truck will jump the posts on the back side of the switch to have the running lights on with head lights...as seen here 1964-1966 GMC Park Lamps

In my setup the parking lights should be OFF when the headlights are ON because the parking lights are used as the turn signals. I just received a new Speedway No. 910-64051 and will try again.

Don, just wanted to verify, your running (parking) lights and your turn signals are 1 lamp with 2 filaments, correct? like a 1157 probably.... is that correct? Our setups are similar so I was curious..

[Don Shillady]

34-40,
Mostly correct. Although I bought my headlights at a NSRA meet, I believe they are from TPI. They have two filament bulbs and a row of yellow LEDs along the bottom in a "smiling" crescent shape.

That's good information to know Rich! I'm glad I haven't cut up my wiring yet and installed a second switch on the parking lights. So if I'm understanding correctly, I should be able to get say a '66 pick up switch without "marker" lights and still plug that into my harness? I understand the mod making the parking lights stay on (although I don't get why..), but I'm not sure how I could modify the existing switch to keep the parking lights off since its not like I have the two wires connected together..

I always thought that it was `60-`65 that was setup that way but LMC lists it to 66, I know for sure `60-65 are because I`ve had several of them and parking lights and headlights independent, but had always thought that GM made the switch in `66, the reason for the jump wire was just to look like the `66 parking lamps on all the time.
