LED bulbs will draw a lot less current, a big plus if you dry camp. They also will put out a lot less heat, making it eaiser to cool you rig. When replacing your old bulbs keep in mind LED's are dependant on potential, that is they must be installed + to + and negative to negative or they will not work. If your fixture is wired backwards, which sometimes happens you may think the LED is bad, so you will have to test the voltage source, and correct if it is wrong.
