2019 tradesmen 6.4 breaks work, no tail lights

[Thepoolboy]

I have no lights at night. Everything else works no problems.

I replaced bulbs. Checked wiring. Can’t find anything.

Any suggestions ?

Didn’t mention checking fuses ?

I was told, there are no fuses to run the tail lights, connected to bcm.
there isn’t. Much info on fuses online

Use a voltmeter to verify that you're getting electricity at the bulbs. then work up from there.
