I'll be curious to know how the under cab lights hold up to mud and/or snow and ice.
They look good and appear to be practical. After seeing them I got to thinking the undercab ones could be hooked up to the door light circuit and use the remote for the bed lights.
Well, they're supposedly water proof and are in an acrylic tube. Same stuff they use around underbody neons, and the ones on my car survived a winter. Even sliding off the road into snow so deep the tires were off the ground.

Also survived -29F temps that winter. They didn't break until I miscalculated where my jack was.... :hammer:
But, these are LED's not neon so even if the tube cracks I can just seal the crack with glue and be fine. The LEDs won't shatter like the neon tube did when my jack cracked the acrylic case.
Not sure about the dome light idea. I'd like that too, but there's a controller box with built in transformer (apparently, very short description on website). Each tube has 4-5 wires each in a plug so you'd have to figure out what they are for. My neons had a 9000v transformer. I have no idea what these would need....

I thought LEDs had low power requirements, but with so many LED's per tube (every inch or so) they might need to bump it up above 12V and split it to each segment. It seems the LEDs are grouped together in sets of 4 or 5. I didn't pay much attention when I stumbled on the chase function. Just enough to notice it was groups of LEDs "moving" down the tube rather than individual ones. Oh, and when I had the plugs at an angle 1 section didn't light up so I'm guessing 1 wire per section, plus a common ground.
Thinking about it now, you might be able to just wire them in parallel to the dome light circuit so each section gets 12v. :dunno: It was cold and I didn't wanna deal with any more wiring! :lol:
EDIT:
Oh, and the undercab ones are on the outside of the frame rails near the top. I'd have to bury the frame before they really get hit with anything. I'm mostly concerned with the bed lights so if the bottom ones die.... f'it.
