Bulbs checked, but behind the bulbs, the headlight harness is a mess. Looks like someone had some "spare wire" but couldn't be bothered with proper splices. Rather than chase trouble, I went by Bowtie Bits and picked up a new harness (only $30.00 before tax). Will head out to the base on Wed and spend some time in the heated auto hobby shop. Your tips were spot on and appreciate your input.
