How To Install Philips LEDs In Your Vehicle


Installing new bulbs in your vehicle can be tricky. Every make, model, and manufacturer has a different method, which can vary in difficulty. We know that if you're a first-timer, or even a seasoned pro, replacing your halogen bulbs with LED can be a daunting prospect.

To help make things easier, we've compiled a list of six popular vehicles - Audi A1, BMW 1-Series, BMW 3-Series, BMW X1, Citroen DS3, and Dacia Duster - and put together a step-by-step guide for installing Philips LED headlight bulbs. These guides should help you see the process of replacing a bulb and how simple it can be to do.

Please remember that this is a guide only. If you're struggling to replace your bulbs, take your vehicle to a local auto-electrician who will be able to help you.


How to install Audi A1 LED headlight bulbs

You will need:

  • A pair of gloves to protect your hands
  • Lamp/torch
  • Screwdriver and Torx screwdriver
  • The new Philips LED bulbs you're going to install

The process:

  • Firstly, make sure your vehicle is switched off.
  • Take a look at the new LED headlight bulb. LEDs have a positive and a negative side, similar to a battery. Familiarise yourself with which side is which before you begin.
  • Open the hood of the vehicle. Using the biggest Torx head, unscrew three of the five screws near the headlight. You'll find one at the back, and two on the top. They'll be the most visible screws.
  • Then, unscrew the two remaining screws using the smallest Torx head. You should then be able to remove the two brackets that secure the headlight unit.
  • Take the standard screwdriver and use this to disconnect the connector from the headlamp. You can now gently pull the headlamp out.
  • Remove the plastic cover and unplug the connector. You should see three pins holding the existing bulb in place. Push one of the pins and gently pull out the bulb.
  • Inspect the existing bulb and make sure that it matches the fitting of the LED you're about to install.
  • Take the new LED bulb and connect the control box by clipping the wires together. Insert the new bulb into the housing and push until it's secure. You'll know it's in place when the pins move back into position.
  • It's now time to connect the control box to the connector. Don't forget the positive and negative sides for the wires: yellow connects to red (positive), and brown to black (negative). Put the control box and the wires into the bulb housing, and replace the plastic cover.
  • Replace the headlight unit, brackets and screws. Reconnect the headlight unit.
  • Repeat the process for the other headlight.
  • When completed, close the hood of the vehicle. You can now turn on your lights and check the bulbs are working. Don't forget to check the alignment. If you need to realign your headlights, take a look at our guide here.
