We replaced our two-bulb 12 Volt fixture under our upper cabinet with three strips of LED
lighting that I bought from Lee Valley here in Canada.
We had to add a wood valance under the cabinet to hide it, and this gave us a place to install the non-contact switch/dimmer. Passing your hand over the sensor turns the light on or off, and holding your hand over the sensor makes it dim or brighten.
Lots of things like this ARE personal preference. I prefer the more natural (blue) light of the LED's better than the warmer, incandescent type of light.
We are still trying to find suitable replacements for the other
lights around the trailer. We would prefer to replace and modernize the fixtures rather than just replace bulbs.
I would ad photos, if I could ever figure out how!
