So I feel like this post will just make my question seem like amateur hour but I guess that's why I ask the best...you guys.

I have a 1967 coupe and it was purchased with after market headlights and backlights. The headlights are those blue tinted ones and they seem to blink once I drive for about 10 minutes with them on. The back right light will also sometimes blink and the brake light sometimes just chooses when it will fully function.
I tried wiggling the back wires and sometimes that makes a difference for the brake light.

In regards to the headlights-I can't really access the wiring without taking the light out and am fearful of this because I might not angle them properly.

Any suggestions?

 

Sounds like the wiring is loose in places, probably the grounds. Those are usually the first thing to check anyway, make sure the ground is clean and tightened to get good conta, Off hand I don't know where your ground connections should be, but someone else will.
