I did a few small upgrades to my 425 this weekend, one of which being LED lighting. The rear lights work fine, however, the front lights are not working after replacing the bulbs. I know the rear ones sometimes don't work right after install and you have to flip them around so the polarity matches up. I didn't have that problem, and they worked right the first time. The front bulbs are the "insert and twist" variety, so no flipping the polarity on those. They just don't work. Any ideas? For reference, the bulbs are 1156 Amazon.com: Aucan 1156 1141 1003 7506 BA15S LED Bulbs White 20-Packs, Super Bright 3014 54-SMD LED Replacement 12 Volt RV Camper Trailer Boat Trunk Interior Lights: Automotive. Do I maybe need to disassemble the wiring and reverse the spade connectors on the lighting assemblies?
