John,
Do you recall what size they are? Five of mine are out, so I thought I would use the excuse to replace with all with LEDs.
Did you replace the fixture, or just the bulbs?
Thanks,
Trent
Whole fixture and used Trucklites. Ft. switched the white and black wires on every one of my lights but they were consistent. Uses a tube of silicone too. The side markers up top were the hardest as they had a very short amount of wire and the wires of all the others were silicones to the fiberglass to prevent moving. Also you need the radius es reflector on the rear ones not the standard. As they are installed on the curve of the cap.
John,
Could that have been because of the polarity of the LEDs?
Trent
Yes I would think so. I had to connect white to black and black to white to get them to work.
