L.E.D. Wiring Diagrams

[Trancer 10+ year member]

With the many questions about how to wire LED's, here is a great set of diagrams on how to wire LED's. I think this should be stickied as often the quesions are asked.

Notice the load resistor that IS needed. For LED/load resistor information check out THIS SITE. Also notice that the Anode on the LED is connected to positive. The Anode is the LONGER lead.

NOTE: If using a light up switch connect the 3rd connection on the switch to ground.

Similar LED Wiring Diagram

Here's a similar LED wiring diagram showing 4 seperate LED's (NOT connected). Notice the load resistor that IS needed for each LED. For LED/load resistor information check out THIS SITE. Also notice that the Anode on the LED is connected to positive. The Anode is the LONGER lead. NOTE: If using a light up switch connect the 3rd connection on the switch to ground.

Multiple LED's Wiring Diagram

Notice that NO load resistor is needed. For LED/load resistor information check out THIS SITE. Also notice the Anode and Cathode connections. The Anode is the LONGER lead. The LEDs MUST be connected in series, NOT in parallel.

NOTE: If using a light up switch connect the 3rd connection on the switch to ground.

12 LED's Wiring Diagram

Notice that NO load resistor is needed. For LED/load resistor information check out THIS SITE. Also notice the Anode and Cathode connections. The Anode is the LONGER lead. The LEDs MUST be connected in series, NOT in parallel.

NOTE: If using a light up switch connect the 3rd connection on the switch to ground.

What size resistor would you need exactly? And how many LED's would you need in series before you don't need a resistor? 4 like in the picture? Reason I'm asking is because i have no idea the resistance of an LED light.

Decado: Four, 3volt LED's take upon a 12 volt load.
