    How many miles are on the vehicle? When exactly do the lights dim? Would this happen to be a 5spd manual? Do the lights dim when you throw it in neutral coming to a stop? How Is your idle? I would do a thorough visual inspection of everything make absolutely sure you don't have any loose connections or wires/excessive corrosion anywhere...How is the battery? I would def. load test it...

    Just replacing parts willy-nilly is not the best or cheapest way to diagnose a problem. You can buy a cheap multimeter for $10-$20 which would have saved you $$$ now and in the future. You find pretty much a tutorial for anything these days on the internet or even you tube. I would have tested the battery voltage first,then with car running,load test battery and clean all battery cable terminals and ohm them out for resistance readings.

    i had a similar problem with mine but not exactly.

    check your under hood fuse box and check to see of the 80 amp main fuse is good.

    if that fuse has any resistance than the issues you describe can be a result of it.
