o i had the same problem the other day . pull your headlight out . you will see the 3 led wires with 3 plugs to each light . pull the plug to the light thats out and you will see the led . pull the led out of the housing and look at the wires . sometimes they slip from the contact point in the housing . so move it and plg it in . if it dont work pull out another one and try it n that slot . if it dont work its done . its easy to replace them . i just dont know about the halos yet
how long havr you had yours?
