hi-beam headlight headache

[lpaine]

Okay, I give up. The previous owner of my 69 gmc installed halogens for the low beams, and kept regular monofilaments?, problem is lows will work fine ,when I switch to high, usually the lows stay on , the high beam indicator won't come on usually, but when it does only the right side low comes on . I suspect this is just probably that cheap taiwanese hi-low switch thats in there(previous owner) I'm just too cheap to go and buy another non -returnable electrical switch, only to find that 's not the problem. I looked at a schematic, I can't find a relay so I can only assume it's the headlight switch or hi-low switch , also the filaments on the hi-beam lights look okay, any comments, jokes, useful info greatly appreciated, thanks in advance. P.s. My condolances on the Columbia tradgedy to all in the U.S. on here. Sincerely lpaine
