The Stovebolt Site Forums The Shop Area The Electrical Bay blinkers and tag lights 1965 c10

Hi folks...

on my 65 c10 stepside, 8 ft bed...
I replaced the bulbs on the tag lights, and they were working fine.
Then a few days ago I noticed that the drivers side blinkers didn't want to blink with the engine off, with the nightime lights on. It would blink slowly, with the engine on and the nighttime lights on Hmn.
Then, last night one of the tail light bulbs wasn't working... and tonight I was buzzing around, I flicked on the driver's side blinker, and it blinked jsut fine... well, I stopped, left the engine on, and both tag light are out. I haven't pulled them yet to check if they are blown or not, but I just replaced them both not two weeks ago... very weird.

Also, anyone know the modern part numbers on the correct bulbs to use in the tag lights?

Any ideas on things to troubleshoot?

Thanks.

First thing to do is get a good heavy ground wire from the frame (not the bed) to each light housing. This should take care of any more problems. Joe

Joe,

Where exactly on the light housing? You mean run a wire from each tag light housing, to separate points on the frame and screw it down somehow, right?

The lights burn, as soon as I install them... and stay burning for a good while, but they eventually burn out... . I wonder if maybe I am running a sissy bulb?

Does anyone know the modern number/brand for replacement tag lights?

Try replacing the blinker fluid with synthetic. The new bulbs require it... :p :p

Get a battery post cleaning brush and use it to clean the sockets really , _really_ shiny clean then smear the inside of the soclet with black moly wheel bearing grease or metallic anti-sieze , this will ensure proper ground of the bulbs , then run a new wire from the mounting stud
of each lamp to the frame , scrape all the rust off where you attach it and use more grease or whatnot (NOT silicone dialectric!) to ensure good grounding .

The twin filament bulbs are P/N 1157 or 1034 , I forget the smaller tag light bulb , we use HD # 631's as they're vibration resistant but only big rigs use them , maybe tractors ? .

A # 532 flasher will speed up the rate of flash a bit .

Good luck !.

Volkswagen Nate, you forgot to ad 99 % of the time at the top of your post.

think twice before you put "metalic" or molly lube in the socket,plain ole bearing grease in a new or non oxidized socket will prevent corosion just fine. use good ground wire same 18 awg as power wire to bulb. clean connections are a must. makey/breaky connections can cause early bulb failure

I bought some Slyvania no. 67 bulbs, and thus far they are still burning. So I prolly had the wrong size... maybe... hopefully that is all it was. The Autozone supercomputer couldn't cross check the bulb I took out... and there's was soem made in china stuff anyway...

I went to advance auto parts and bought those sylvania's and things are good so far.

thanks for all of the tips folks!

things to keep in mind.

I love this page!
