For lighting with small current draw, it should be safe enough to take it from the lighter plug. Best case is to run directly from the battery with proper fuse. Assuming you only want it on when you open the arm rest then install a pin switch which when the arm rest is raised, turns on the light. It would be a good idea to have an on/off switch for over ride. But to each his own, but running anything with the engine off for a long period of time will eventually drain the battery as Kenchan indicated. A single LED will take weeks if not months to fully drain a battery however. Contrary to what most people think, a car is not totally "off" when the key is removed. Ancillary systems are on all the time including (key sensor, clock, alarm, etc)
