#1 You save time and money, because our leds are ready to use by battery 6V-12V+ DC!
#2 Quality! All resistors are attached and sealed with wiring.

· They do not consume more than 30mA each, so you don't need to worry about straining your battery. (Our high power leds consume much more)

· They do not need any other resistor, it is already built in. Only hook up in Parallel, Never in series, series will make them dimmer.

· You cannot hook LEDs to AC (house power), they need direct current DC found in batteries/cars/boats

· You can hook them in your house using an AC-DC adaptor (6-14V sold everywhere, look below for instructions.

· The difference between 5mm and 8mm is not the brightness, but how big the glass size is. 8mm will give wider beam.
