LED taillight wiring colors

[Zorba]

I have a set of no-name LED Jeep tail lights I'm going to use on a trailer. They have 4 wires. I am GUESSING they'd pin out as follows:

Black: Ground
White: backup
Red: Stop/turn
Brown: tail/running

Before I go to the trouble of ringing this all out - anyone have any ideas?

Every pair of cheap no-name lights I've ever seen has different color wiring for each function. There is no standard they follow.

I know you don't want to ring them out.........but it's 3 wires my man

A quick trip on Amazon show this to be true.

how about a solid- I like your guess! Makes the most logical sense but I would do a jumper on the battery -assume black is ground and test the rest.

Yea, I was afraid of that. No standards, and possible A/C wiring colors.

I like my guess too - but obviously I'll have to ring it out. It was worth a try asking at least!
