LED Motorcycle Headlight

Step 4 Part 1: Wiring

Part 1: Step 7
Place the LEDs into the array plate you made making sure that they are appropriately oriented with their leads bent to make series sets of 4 LEDs.

Solder the sets of 4 LEDs together. Solder a resistor onto the positive side of each set. I would recommend testing each set with a battery or variable power supply to confirm that you have them wired in the correct orientations. If on LED is wired in reverse orientation that particular set won't turn on.

Solder all of their negative leads together to make the Neg- input, then solder the leads of all of the resistors together to make the 12v+ input.

Solder leads of wire onto the Neg- and 12v+ inputs. Mark the ends of the leads with tape or heatshrink.

Part 1: Step 8
Use a battery or variable power supply to test the fully wired array.
Once confirmed that it's wired correctly, use a dab of super glue or hot glue at the back of the LEDs to adhere them to the array plate.
Once the glue is dry, Assemble and test assemble the array into the fixture. Test again with the variable power supply or battery.

If super glue is used, make sure to take the fixture back apart and let the super glued parts dry out in the open for several hours. The fumes that super glue produces in the first 2 hours of drying will in enclosed spaces stick to and whiten fingerprints as well as fog up most clear plastics.
