      Ok but

      Posted by Robert Fomenko on 30th Dec 2022

      So I bought the complete kit of 16 lights 2 years ago and just finally got around to installing them. I have a 40 ft class A with a single rear axle no tag. The wires are not long enough to go from the front where my wiring buses are, to the back. So I bought the expansion kit thinking that that would allow me to put additional wires and lights after the axle but no it doesn't work like that. I would have much preferred to have another long harness and a few of these y connectors. So I had to basically install the lights between the front and the back axle. Did not have enough wiring to get around the axle remembering that I had to go up and over the wheel wells. Which is a shame cuz I have six lights now that I have enough no way to use them unless I buy another kit I guess. Don't want to do that. It gives a little pools of light under the coach instead of one continuous light. M4 Note: Please contact us with any tech of spec questions at any time. We have a expansion wire kit on the website that would extend some of the lights behind the rear axle, but most with pushers do not put them back there due to the harsh environment. The product descriptions on both the main kit and double up kit have specs and diagrams of all of the wire lengths as well as pictures of the results of a 8 pod kit. Where you place the lights will also distribute the light more, higher or sideways distribute the light. The end result should be a strong glow of light under the RV, not a bright work light, as it is a accent/mood lighting system.
