No reverse lights

[TreverStevens]

I swapped some LED bulbs into my reverse lights back when I was doing my engine(5.9L)/trans(NV3550) swap and now that everything is up and running the lights aren't working. I put a new reverse light switch into my transmission and checked the fuse in the glove box assigned to the reverse lights but no change. My brake lights and turn indicators work. I pulled the lights yesterday and checked everything was connected and checked the plug in the body within the tub. No corrosion or bare wires
I could immediately see. Where do I check next or what do you recommend to chase down this problem?

Some LEDs are polarity sensitive....
Remove and insert the LED in a different orientation....

Test the bulb socket to see if you’re getting power. If you aren’t, test before and after the new trans switch. If you don’t have power at the switch then probably a break in the wiring somewhere.

I believe those are an 1156 which will only go in one orientation. The tail/brake bulbs that could happen to.

Also be sure the bulbs used were 1156…if you tried an 1157 that won’t work.
