Purchase a length of PVC pipe. The length of the pipe will be the length of the strip light.
Purchase a LED light strip as long as the PVC pipe.
Pull the LED light strip over the length of the PVC pipe.
Mark where every LED bulb is on the outside of the pipe.
Drill a hole in each marking made in Step 4. The holes should be the same diameter as the LED bulbs.
Run the LED strip through the PVC pipe.
Push each LED bulb through each of the drilled holes. This can be a little tricky, as the bulbs are not easy to reach. Use a yard stick or other long object to help guide the light. Use tweezers to pull bulbs from the outside of the pipe.
Use Super Glue(or similar product) to bond the bulbs to the PVC pipe. Wait for the glue to dry.
Attach an LED control module to the LED lights. The light strip will clip to the control module. There are a variety of modules to choose from. Determine if you want a battery or electrical (outlet) powered control module. Test once the power is connected.
