Installation Of 3 Wire LED Marker Lights

Question:

Hi I just pickup some led marker lights for my camper after opening them I see they have 3 wires black,red and yellow. My old lights have only 2 wires. I am thinking one of the wires would be for a turn signal but I dont need that. Can you tell me what 2 wires I need to use just for the marker lights. Thank you

We don't carry lights with those colors, so you will need to test them based on function. Normally black and red are power and white is ground like you see in the # STL69RB. I would try the yellow as ground. Red is most likely the turn signal and brake function and black is most likely the constant running light.
