How To Wire Led Indicators. Its likely though youve already read the Wikipedia page about Series and parallel circuits here maybe a few other Google search results on the subject and are still unclear or wanting more specific information as it pertains to LEDs. Repeat on the second set of wire leads.

When it comes to wiring more than one LED to a power supply there are two options. The load resistor goes across the light bulb connections between the supply and ground. This is the safer better way to wire leds in parallel with resistors and also ensures that you dont make the mistake that i did accidentally.
The first option is to wire them in series and the second is to wire.
Start by bolting on the light with the M8 Nylock nut and Washer provided. The colored plate fits on top of the bulb but under the reflective plate is the wiring. The load resistor goes across the light bulb connections between the supply and ground. Repeat on the second set of wire leads.
