Step 6Solder LEDs
iImage Information

Use the holes in the casing as a makeshift fixture to hold the LEDs in place while you solder the LED legs together as shown in the photo. This helps keep the right distance between each LED while they are soldered together. Keep the LEDs in the same orientation so each positive leg is connected to the other positive legs, and each negative leg is connected to the other negative legs. You should bend the LED legs close to the LED body because you dont have much space in the battery holder.
