side marker lights
The side marker lights in my 1971 C20 when on turn signal blink only in the front, my 1970 GMC don't blink at all,front or back.The wiring diagram I have doesn't have marker lights on it.What is correct? Thanks in advance for the help.

Re: side marker lights
Both are correct. The blinking side marker started in 71.

Re: side marker lights
That is true but I'm doing it for safety reasons.

Re: side marker lights
When you do the rear something weird happens, i think it has something to do with back feeding through the brake lights or something similar. That's why the factory only did the front. The brake lamp cancels on the side you are turning, but if you have the turn signal flashing on the side marker?? I forget....I tried it years ago. Didn't work out right.
EDIT, something else is when you step on the brake, being the same filiment at the turn sig, the side marker being already lit up by the driving lamps. Like I said it got weird when I tried it Last edited by kwmech; 03-14-2020 at 08:41 PM. |

Re: side marker lights
I did mess with it a little bit before it started raining.I have the turn signals working in the rear side markers but no lights in parking light mode (rear).We will see what tomorrow brings.
