The car is a 2012 Tacoma pre-runner. I got in it last night and turned on the headlights. The low beams came on just fine, when I pushed the lever forward to engage the high beams, the low beams went out and all I had were weak fog light. When I return the lever back to normal the low beams come on. I looked and there is only one bulb in each headlight. Not sure what is going on?
