    ok ive got an 88 blazer with 4 head lights, anybody know how they are supposed to work? the truck has a snow plow installed also and i have good reason to beleave that the wrong wireing kit was used. anyway i have replaced all of the bulbs (glass sealed beam deals) i got the (low beams?) top two to work are they suposed to be dual fillament bulbs? they seem to be working fine, when i switch back and forth between high and low i can see them change but the bottom two dont do anything. im sure there will be some wireing that i will have to figure out but im not actually sure how they are suposed to work which makes it pretty hard to fix :) when the high beams are on are all 4 suposed to be on? it seems that way, i guess the top 2 switch fillaments and the bottum 2 turn on right? thats how it seems to me like its suposed to work but i have seem kits to keep all 4 on so im not sure what was alltered on my truck any help you guys can give me or any good sorces for info would be great, thanks

    If U have 4 lights, they are all supposed to be single filament.
    They might have put dual fialaments in the top and cut the bottoms so they could have brights with the plow on, mabey the tops clear the plow?

    thats what i would have thought but even the computer at the auto parts store said dual fillament bulbs, allthough that could just be for universal purposes. but there is virtually no difference between the two settings so they deffinatly still need the other two lights.
