Weird lighting issue

Wondering if anyone has had this issue and can help me out.

When I turn on my headlights, both of my turn indicators come on the dash, (but do not blink) and the headlights are very dull, particularly the passenger side.

Neither are bright enough to use for night driving.
I'm figuring a short or crossed wire, but wonder if anyone else had and solved this wiring issue.

Thanks in advance.

Check your grounds on the core support. You should also check the bolts attaching the core support to the passenger's fender, and the battery ground on the fender support If the grounds are bad, the lights will try to find another path for current flow. In your case it is through the turn signals. Checking the battery ground to the engine, and the engine ground to the body.

My brother had a somewhat similar issue years ago with a Plymouth that had a 440 in it. When he tried to start the engine, the solenoid would click, but the starter would not run, although the headlights would come on dimly. It turned out to be the engine block ground. Some "intelligent" engineer had the engine ground go to a bolt that penetrated the water jacket.
