So what did you do to your Truck Camper today?

Also think of this...With incandescent bulbs you have not only the leak factor which will lead to corrosion and socket failure as well as the potential for multiple leak points as well as a higher amp draw, LED lights are generally molded units that are one piece with less potential for water incursion thereby less failure potential, Incandescent vs. LED lumens is a clear winner with the LED being higher with less amps, Your alternater is already working hard enough with the stock configuration and then you put additional load on the vehicle so any advantage that you can gain will be a bonus. Just my 2 cents
