First time posting here with a bit of a head scratcher on my 2019 Ram ProMaster 2500.

I've got these cool LED strips in aluminum tracks along the ceiling, and they've been awesome for like 5+ months.
But now, they're slowly dimming from the end where they're wired up, and that end feels noticeably warmer. Super annoying!

Is this a wiring thing? How to get it back to it used to be?
I even put in 12V line conditioners for my Maxxair fans (each light/device has its own fuse, too), so I'm scratching my head

Anyone run into this before or got any ideas what's going on?
 
It sounds like classic voltage drop to me. You might want to check the gauge on your wire run. Those strips can be picky if they're not fed properly.
 
yup, I agree with @Primadonna, should be voltage drop, even with fuses and line conditioners, if the wire gauge is too small or the run is too long, the lights closest to the power source can overheat and dim out faster, check the wire size and maybe shorten the run or bump up the gauge.
