question about 12 v led lighting?? (UPDATE)
going to install the strip of led lights under my awning and have them wired to my outside porch light. looking at the picture below, do i cut the black wire (right there) with the adapter connecti...

Is it on the output or input? Are you using the "power pack" connected to 120V or have you changed that? Are you feeding the control box with 12V from the RV system? Is "power pack" the piece that is a brick transformer with a toroid attached to the output wiring?
Guesses: Since the controller changes LED illumination among a combination of different LED's of different color, it may do that by controlling voltage to the string. Any change in the voltage input to the controller may effect the output. Brick transformers rated at 12V may be outputting up to 16V. It may be that the controller, if connected to RV system 12V, is not getting enough voltage to operate correctly. You could measure the brick transformer's output voltage and your RV's system voltage to see if there is a big difference.
yes the barrel plug is after the transformer as seen in the LED link.and i cut that barrel plug off and am using the same plug with the 110 and the 12v. just rewire them when i test them to either system.
UPDATE, talked to the guy that makes the sockets and he states no kind of resistors or anything...
whet out this morning and tried the lights again and switched the polarities around etc and still only the blue lights would light with no remote functions.
took the lights inside and tried them on a interior light 12v. and the same think, only the blue light would come on no remote function.
thinking that maybe something wrong with the trailer wiring i took the lights into the garage where i have a spare 12v battery and wired them directly to the battery and still just the blue lights would function with still no remote function,
only other thing i noticed was that on the 4 prong plugs on the lights and the one coming out of the white receiver there are little arrows on each side. i assume that the arrows are suppose to match up when plugging in. BUT when i match up the arrows even the blue lights don't work. when i reverse the arrows so they don't match up the blue lights work.
could the white receiver (controller) be no good or any other suggestions?
thanks again for the help.
