This is a 24 LED panel light, you can wire it into the exsisting fixtures in your RV. Each light is only $0.84 when bought in a pack of 10 for $8.40.
http://www.aliexpress.com/item/24-3-core-5050-smd-led-car-lamp-plate-reading-lamp-roof-lamp-rear-lights/1050754726.htmlI just bought 4 more lots, about $33 including shipping. Should arrive in about 3 weeks. I am installing some of them on a friend's house, where I installed a 90 watt solar panel, 25 AH battery, and solar controller that automatically turns on the lights after the sun sets. So the panels are mounted on the eves, pointing down, giving off more light than a malibu light set would do.
To wire the house, I have #18 gauge wire strung around the house protected by a 7.5 amp fuse, and running 8 of these panels is less than 2 amps. It lights up the front of the house pretty well, and I will put 10 more in the back yard.
To install these LED panels in my RV fixtures, I first cut the wires to the exsiting bulb base, then wired in 2 of the "adapters" to the +12 and ground wires using small blue wire nuts. Then remove the double sided tape from the back of the LED panels, and apply that to the fixture, pointing down.
I put two of the 24 LED panels in each side of the fixture in my bathroom, and have plenty of light with only 0.4 amps power to run all 96 of the LED's.
For my porch light, I also removed the wires to the bulb base, and installed 4 adapters, using wire nuts, and sheet metal to attach all 4 of the panels to face near the cover, and the cover holds them in place against the new metal mounting bracket. So they shine outward. IT lights up the side of the house pretty well. The 315 watt solar system keeps the battery full, despite also running the CO meter and propane leak detector full time as well.
For my pump on indicator light, I used a 12 LED panel that I had purchased earlier. It also lights up the bathroom and kitchen well enough to see by when walking around at night.
For replacement running lights, I bought but have not installed some T-19? bulbs that have 5 LED's per bulb, and will directly replace all of my running lights. I bought about 20 of them for around $17. My plan is to install them some day, and it will reduce the amperage going to the running lights from 14+ amps to less than 3 amps, also providing more light, and at 12.5 volts, not the reduced 9.5 volts now due to the excess amperage that the factory installed bulbs currently take. WHile installing these replacement LED's, I will have to keep the running lights on, because the replacements will fit both directions, yet only light up when the +12 and ground are installed correctly. I think that this is the same type base as used in 12 volt malibu lights. I have seen the T-19 base sold with anywhere from 5 LED's to 18 LED's in each bulb. I bought the 5 LED for the best price and also a weak bulb light output consistant with the low wattage of running lights.
Good luck on your LED light set up.
