How to Build an LED Camcorder Light

To improve the visual ability of your camcorder in low light or complete darkness, you can make your own camcorder light.


1. Gather all of the materials you’ll need to finish this project. These are listed further down in the section titled “Things You’ll Need.”

2. Find some suitable elasticized fabric.

3. Measure the circumference of the camcorder lens, or the mounting point where the light will be attached, whichever is larger. After that, repeat the process for the elasticized fabric.

Cut the elastic to the appropriate length. Add a few centimetres or inches to your measurement in order to account for any possible overhang.

4. Apply a dollop of glue to the edge of the elastic strip with the glue gun, and let it dry. While forming a circle, overlap the two edges to form a ring.

5. Hold this in place till glue hardens, approximately 20 seconds.

6. For the next few steps, refer to this wiring diagram.

It is important to note that the value of a resistor is represented by its colourful stripes. For a 470 ohm resistor, the stripes on the left side of the resistor are yellow, purple, black, and black, and the stripes on the right side are brown.

Allow enough slack in the wires to wrap around the entire lens and then some when you’re measuring them for the project.

7. Please read the “Warnings” section below before continuing with the next steps.

8. Plan out the light circuit before soldering.

9. Connect the resistor to the positive terminal of the first LED using a soldering iron. Make a second pass through the soldering iron to connect the negative terminal of the first LED to the positive terminal of the second LED.

This is an example of a series circuit. Repeat this for each of the three series circuits in the circuit diagram. Refer to the wiring diagram once more.

10. When you are finished testing the circuits, connect the positive lead (the end with the resistor) to the positive side of your battery and the negative lead (the negative side of the second LED) to the negative side of your battery again. If the light turns on, this indicates that the lights are properly wired. If they don’t, double-check your solder connections for damage.

11. Solder on the wires (see “Things You’ll Need” below for sizing).

12. Fill in all of the gaps between the electrical connections with glue to prevent the components from touching and arcing. This will also help to protect your light from the elements.

13. Glue the three sets of lights equally around the elastic strap that you created earlier.

14. Combine all of the wires coming from the light circuits into a single bundle (there should be 3 positive wires and 3 negative wires). Using these wires that have been striped, twist them into each set of three wires to form one wire. There should now be two wires in total. This completes the series circuit you were working on.

15. Solder the negative wire to the negative end of the battery connector.

16. Solder the positive end to one end of the switch. 

17. The positive wire from the battery connector should be connected to the other end of the switch. 

18. Plugging in the battery and turning on the switch will allow you to check your soldering work. All of the lights should be turned on. If this is the case, double-check your soldering.

19. Cover all the connections in glue for weather proofing. Allow to dry.
