How To Convert Motorcycle Headlight Into Bike Light

Equipping your bike with a headlight is great if you want to get a clear vision at night. It helps you stay safe on the road and avoid accidents when you are riding in dark places. Did you know you can convert a motorcycle headlight to a bike light?

If you are wondering how you can do that, I will give you an instructable guide on how you can do that with a 100 watt LED headlight common in motorcycles. It is easy to that and you don’t require fancy tools or equipment. Let’s get right into it.

Materials you Need:

  • Heat sink (100x100mm) and heat sink paste
  • Some basic tools like screws, drills, nut, bolts
  • Soldering kit
  • 20-100W LED chip 12 V
  • Switch
  • Reflector and 60-degree lens
  • Zip tires
  • Wires
  • Drone battery
  • XT 60 connector
  • Epoxy glue in two parts

1. Heat sink and Fit the Lens:

Use a drill and make some holes on the heat sink and then apply the sink paste. Place the LED chip carefully. Mix the glue in a ratio of 1:1 and apply the glue mixture on the lens, LED, and reflector. Put the lens and the reflector on the LED and wait for it to dry overnight. Cut some holes and position the switch depending on where you want it.

2. Electrical Connections:

Smear some flux at the wire ends and tin those ends with a soldering iron. Additionally, ensure that all connections are insulated with tape and avoid short-circuiting the battery. Connect the battery with 10A fuse and then the battery ground to the bicycle body to eliminate electrostatic shock. You can also use a battery management system to protect the battery.

3. Installation and Testing:

The next step is to install the headlight on your bicycle and test if it is working. You can do the LED assembly using a nut-bolt and a clamp. Place the battery under the bike seat or on the frame. Hold the battery and the wires well in place using the zip ties. You can keep the switch on the handle to make access easy.

You should also consider having a bigger heat sink to make cooling the LED easy. Alternatively, you can install a fan to enhance the battery performance. You should also know that the LED is high power so sometimes they don’t last long. Therefore, you can have two batteries or consider a smaller wattage LED.

You have now successfully installed a motorcycle headlight on your bike and you can ride safely at night. The whole process can take you about two hours to complete and it is easy to do that if you have the right tools.
