intro/headlight problem on 83 Regal

[s.pliskin]

greetings

New to the forum. Spent a bit just browsing the QnA's.

I got an '83 Buick Regal, 3.8 w/barely 100k on it, THM350.

Only problem I got w/it right now is sometimes I'll be driving down the road and the headlights will just start flashing on and off.

When I first got it, only the BRIGHT's would do it, so I used dims.

NOW I have to use the brights because the Dims start flashing.

Strange, and stumped.

thanks
