You need to go by the manufacturer's specifications.Hi Steve, is it correct in saying an L.E.D can draw upto 20 milliamps or less? Being as there working voltage range is between 2-4v.
Your existing side lights are incandescent. They require far more power than LEDs do. LEDs and incandescent bulbs are very different critters.Just done some research my side lights are 5W bulbs times 2 =10/12 which gives me just under 1amp current draw from this calculation can I work out the resistance in order to give me some kind of indication of a resistor value?
LEDs as components generally do not have markings. Basically, there are only clues as to which lead is the anode (+ side) and which is the cathode (- side). Usually, the cathode lead is shorter, and/or there is a flat spot on the rim of the LED.What should I be looking for on the L.E.Ds if there are any scribings.
Well, a resistor does not power an LED; it functions as a current limiter to prevent excess current from flowing through the LED.When I have purchased a suitable resistor to power my L.E.Ds am I best wire it in series power supply side or wire it in on the earth side of the L.E.D?
