my twat nav and 12v accessory socket both run off the side light feed with no need for relay. the sat nav is a 5v system (with a circuit to drop the voltage in the mount usually) and most phones are 3.7v. as long as you dont try to run heated clothing or a ciggie lighter off it you'll be fine. i fitted leds for my side lights as well which means that the current draw with all accessories (8w) going is actually less than 2 sidelights (10w).
The problem with socialism is that sooner or later you run out of other people's money!
