Northstar LED tail light erratic

I have LED multi bulb tail lights on my camper and the driver’s side tail light has gotten erratic. Sometimes all the LEDs light as they should. Sometimes they all light and then only about 10% stay on and at other times different groups light in random patterns. Light on the passenger side works fine. So far all I can think of is tail light has to be replaced, $100.00 for 3 year old taillight is not good. Any other thoughts.

switch bulbs left to right and see if the problem follows.

Once I get home, I’ll give that a try. Hate to do too much while camping unless I have to. As an aside the lights clearly have a “top” for orientation and Northside mounted them sideway. That may be why there is water around the bulbs in the lights on both sides.

I replaced the taillight on my 850SC with:

Kaper II L15-0088BLK Red Trailer Stop/Turn/Tail Light
Amazon Amazon

much less expensive.

Maybe check the connectors. I see dust buildup and sometimes moisture under the lens of my Laredo but have not had a problem with mine. Could be the connector plug from the TC to the truck is dirty.

You probably already know all that but sometimes I forget to clean the plug connectors.

All good suggestions so far so I'll just add, with what you described I would just replace the light. It sounds internal.

I agree. Since the light on the passenger side is fine, it’s hard to make a case it is anything else.
