Variety mainly comes from the size of the bulb or the size of the base. The various sizes are :

Procedure for Replacing Your Headlight Connector

Running a vehicle with working headlights is detrimental to road safety. Running without functioning headlights is illegal. To avoid being fined and for your own protection, replace the connector when it is worn out.

Of course, replacing this socket isn’t as easy as pie. If you want to replace this plug, you’ll need to learn the proper way to do so. You’ll need some simple tools.

Tools required

  • Socket wrench
  • Electrical tapes
  • Wire connectors
  • Splicers

Steps

  1. Remove the negative terminal using your socket wrench.
  2. Remove the socket and bulb from the headlight.
  3. Find the wires about three inches away from the fixture, and cut them using your splicer.
  4. Remove about 1/4th inch of the wire coating out and pull the wire out.
  5. Connect the old wires to the connector you want to install using your splicer.
  6. Twist the wires together according to their color (note the red and blue stripes).
  7. Reinstall the bulb and the fixture.
  8. Reinstall the negative terminal.
  9. And you’re done! Check if the lights work correctly.
