    I am having an issue that is strange to me.

    When i go to turn on the headlights, only one will turn on, and the other will remain off. If i turn off the lights and turn them right back on, whichever light was off, will turn on and the other light will remain off. If i repeat the process, both might turn on, or they may change states again. eventually, both lights turn on and stay on for the night.

    My thoughts is there are relays that may need to be changed and there are getting old or bad contacts.

    Anyone else have this issue?

    i search for this issue but didn't bring much up..ofcoasre assuming i searched for the right phases.

    There is only one (column) switch contact and one relay for both L/R low beams, so it won't be a switch contact or relay if one headlight is coming on.

    If it 1 switch for both, then check the earth on both sides

    For info, the headlight (low beam), headlight (high beam), side marker and turn light all share the same earth on their respective side (i.e. two earths for all the front lights).
