Mine crapped out after 3 months on my 2015 and they were warped and not very bright so I just replaced the whole thing with a new plastic channel and light MUCH BRIGHTER
and not a big deal to take off the old track and install the new, the old track is connected to the awning but I just grabbed one end and pulled it off, then you just clean the area with rubbing alchohol and stick the new track on then stick the light strip into the channel and wire it up and you are done, not sure how long yours is on your model but but mine was about 16 ft and this is where I bought it
