Intermittent high beams only. Low beams solid.

I threw a new dimmer switch at it but the problem persists. The high beam indicator goes out along with the lights if that's a clue.
This is a '69 LeMans Convert.
Any ideas?

New dream catchers!

I fired up the Pontiac New Years Eve to show a couple friends and the next day I found a couple of brand new Dream Catchers! And I always thought the whole Indian thing was just a marketing tool!
