This video identifies 3 benefits of replacing your incandescent RV light bulbs with LED’s. I bought a few packs of 12 SMD (Surface Mounted Diodes) to replace my 921 sized incandescent bulbs. Installation was super easy and only cost me about $25 from eBay. I am very pleased with the color and brightness. I am even more pleased that I can dry camp and not be so concerned about the lights draining my batteries. These lights draw about 1/8th the current and have comparable brightness.
