I've been googling and searching around but I can't quite find my answer. I'm sure it's a ground issue of some sort I just want to get an opinion, after a bit of thinking I guess it could possibly be a indicator switch? Anyway here it goes..

Headlights off -- left and right indicators work in front in either direction but super dim... Both taillights blink together no matter which position.. dash lights light up correctly for the direction the switch is in.

Park lights on and also headlights full on -- both dash light direction indicators are illuminated and trying to put the blinker switch in either direction doesn't do a thing.

Also maybe unrelated hi and lo beams work but the high beam indicator on dash does not light up, probably just a bulb but I I'm pretty sure stuff goes through the dash before getting out to the lights? Maybe I'm wrong.

I've tried new flashers, I had an extra headlight switch so I install that. I cleaned up all the grounds on the rad support and alt bracket. I've tried cleaning up the bulb sockets as good as I could but no luck. I also got rid of my trailer light harness that was very poorly spliced in. All that fixed was the tail light dimness, they are bright now. But the front side markers and indicator lights are super super dim like I can hardly see them in the dark.

My to do's tomorrow are measure voltage at the front sockets, search for any extra grounds and maybe even add a couple. Any extra input would be great!!

Yes, ground issue. Try running a jumper wire with good sharp alligator clips from the bolt where the front light harness is grounded, right to the battery ground. The sheet metal could have lost it's ground. Rust never sleeps.

Well I'm an idiot. I guess a visual inspection isn't enough on these bulb sockets.i went to wiggle the front indicator wires right as they get into the socket and wouldn't you know it both the side marker and the front indicator got way brighter. No issues now. Just need to order some new sockets and get them spliced in
