Step 4Mount LEDs
iImage Information

Its now time to mount the LEDs. Grab your bag of LEDs, and insert three into a row. Ensure that the polarity is kept constant. All of the positive sides (longer lead) should be on the same side of the plexi glass. Next using needle-nose pliers, bend the leads into a square as shown in the picture below. Next, solder the leads together. Repeat this process for the other touching leads. The resulting soldered connection should be enough to hold the LEDs in place. Trim off any excess lead, but leave the main (+) and (-) long as shown in the picture below.
