Same issue with our 2005 25 Intnl CCD. Read of another member creatively connecting one to the dump light to manually activate a backup light. This could allow use without needing to be TV connected and in reverse. Looked and bought other LED lamps but didn't like the non-factory look in placement.
Thanks to Amazon, found a sealed waterproof Kalwell brand 22.00. With 9" aluminum sheet 12.00 a few bends extended license plate bracket. Made small access hole below factory LP light hole and below lateral support stud to near rear hatch. Allowed access into the forward side storage courtesy light wiring. Cut in a small rocker switch (recessed/inset to prevent accidental activations) to separately control the BU light or for courtesy. Keeps it safe, fused, clean and on a 24/7 power to use anytime without TV connections. Works looked great and REALLY kicks out the lumens !
Relaxing is hard work
