Relays?Ok are they hard to replace and do they control the hi and low beam to the headlights also? mancoman

Easy to replace! unplug. Generally headlights don't use a relay unless they are dark sensing.Most headlights have just a switch that interchanges the low/high (2 wires for low-3 wires for high)
