i just want to know..
if i had 4 blue LED's, and connect them to the headlight switch. how would i do so? would i just connect the LED's in series and connect them to the headlight switch?
or would i need to connect them to a resistor. honestly.. i have no clue
sorry for the dumb q
basically i just want to light up 4 blue LED's.. how would i do so?
thx

Connect in series with each other. They probably don't matter which gets + or -, just connect one lead to one side, then chain together, then last lead from last bulb to ground.

It depends on the voltage rating of the LED's. If they can handle 3V a piece, you can run them in series. And, YES it does matter which side is anode and which is cathode. they all need to be facing the same way.
-|>|- -|>|- -|>|- -|>|-
If one is switched, no voltage will pass through them.
If the LED's aren't rated for 3V or more, you will pop them.

I'm pretty sure you can wire in a resistor to bring the voltage down.

you should add a resistor anyways. for current reasons.
