    Hey guys!

    Couple of months ago both of my low beams went out, didn't think much of it and just used my high beams.
    Finally one of the high beams went out and I bought new H4 bulbs to replace.

    After an hour of messing with the headlight assembly and trying to get the plastic thing off I installed my new lights....but low beam still doesn't work.

    I checked all my fuses and they are also good.
    What could it be
    Thanks

    There are four fuses associated with the headlights, one for each filament on each side. If you are sure that the low beam fuses are good, then the most likely failure point would be the DIM relay.

    I hope you are able to figure this out soon so that you can stop blinding oncoming traffic and having those drivers mutter (or worse) about you.
