Marker lights/right brake and blinker not working
I have a new issue. When the marker lights are on or if I turn on the headlights the right blinker either blinks fast or doesn't work at all. The right taillight is lite brighter than the left but does not blink. Has anyone had this issue? This is on a 2021 Momentum 350G.

What TV do you have? There have been issues with some late models, Dodge and Chevy
A couple places to check. The connection box where the 7 pin plug cable ties into the trailer wiring. Look for shorts, loos wire nuts and loose ground connection.
Second place is at rear of trailer. Look for the wire splices coming through the frame. Also pull the taillight and check the wiring behind. With lights on wiggle the connections and splices.2018 Reflection 150 Series 220RK 5th wheel with 6K axle upgrade.

Thanks for the info. I will be looking into the connections in the pin box area today. I will also unplug the TV and check the blinker and brake light.

Fast blinking or outright failure can be caused by a blown incandescent bulb (i.e, not LED).
I'd check the truck lights, first.
Most likely culprit?

I traced it down today and fixed the problem. It was right LED unit, brake light and turn signal. Purchased a new unit and worked properly as soon I hooked it up.

I learn something new every day.
I didn’t figure an LED would burn out, as it is unusual for them to fail.
Glad you found it!2023 Reflection 315RLTS
