  1. 1

    Drill holes to the size of your LEDs along the length of the PVC strip. Each hole should be about a quarter of an inch apart. Sand down any rough edges.

  2. 2

    Slip a LED in the first hole and glue in place with a dab of hot glue. Take care to to cover too much of the LED's leads. Position the LED so that the positive short lead is on the left of the strip and the negative longer lead is to the right. Repeat this step until all the holes have a LED secured into place.

  3. 3

    Bend all of the LED leads so that they come in contact with the lead next to them. Keep in mind that a positive lead needs to come in contact with a negative and so on. The first and last lead will be left unconnected.

  4. 4

    Solder all the connecting leads together. If the leads are spaced too far apart and can't reach each other, use a small bit of electrical wire to bridge the gap. All but the first positive lead to the left and the last negative lead to the right of the strip should be soldered together.

  5. 5

    Solder one end of wire to the positive post of the battery pack and the other end to the negative post of the toggle switch. Solder one end of wire to the positive post of the toggle switch to the open positive LED lead.

  6. 6

    Solder one end of the wire to the negative post of the battery pack and the other end to the open negative LED lead. Tape the long wire to the back of the PVC strip.

  7. 7

    Cut small pieces of black electrical tape and wrap all exposed wire and leads to prevent any metal from coming in contact with other metals. Insert batteries into the battery pack and flip the switch to illuminate the LED light bar.
