I got tired of how bright the LED ceiling lights are in my TT and decided to find a way to install a dimmer.
Here's what I used and they work great. It installs directly to the wiring for an individual light. I don't think it's possible to have or find a controller for ALL the LED ceiling lights in a Jay Flight SLX as it's a complicated/weird setup for newer models.
It's a remote dimmer and has great control over how much it's dimmed. We hated how bright just a SINGLE LED tap light was in the TT and there were 11 of them in our 174bh. I just put a couple of these controllers on a couple lights and it's much better for adjusting the light at night or for reading in bed!!
