Step 2: the led. leds come in different sizes, brightnesses, voltages, colors and beam patterns, but the selection at radioshack is pretty small and so i just picked up a couple different leds from what they had in a few different brightnesses and voltages. Step 3: connect the led cathodes to the negative battery terminal. using a similar strategy to how you connected the positive side, solder a length of wire to the cathode of each led (shorter leads) and combine them into a single wire that gets soldered to the negative wire of the battery pack.
4. plug in the adapter to power the strip. once the wires are securely attached to the adapter, plug in a power supply cord into an outlet. then, plug the power cord into the slot on the adapter. the lights on the strip will turn on. [4] cover the led strip with a plastic or aluminum casing to keep them protected. Avoid crossed connections. unlike 120v electrical circuits, low voltage circuits for led lighting use stranded wire. it’s a common mistake to leave one or two strands hanging loose when you connect the wire to a controller. the errant strands then contact another terminal and cause a short. Step 1: connect the led light. dc wires typically use stranded wire, so ensure you twist the strands before connecting the wire. if it’s an led strip light, you might require a soldering iron to connect the wires to the strip, whereas some types don’t require any soldering. only 2 of the wires are for the power source. Learn how to wire leds in series, parallel, or series parallel circuits with constant current drivers. find out the advantages, disadvantages, and requirements of each circuit type for led lighting applications.

Rearranging the first formula to solve for resistance we get the following: r = v i. if we solve for resistance then we get something like this: r = (15v 2v) .020a. the voltage value needs to be what is left over after the led's needs. in this case, our maximum voltage is 15v because it is from a vehicle.
