  • Phillips head screwdriver


  • Mitsubishi Outlander taillight assembly


  1. Firstly, open the trunk so you can see the two screws on the side of the taillight assembly.
  2. Remove these two screws from the inside, and pull the taillight assembly off of the vehicle. A little bit of force may be necessary. The tail light is held in by retaining pins that snap out.
  3. Remove the turn signal bulb connector by pressing the plastic tab and pulling the connector out.
  4. To remove the electrical connector from the LED brake bulb, the plastic connector attached to the tail light must be twisted counterclockwise and pulled out of the tail light housing. This will expose the male connector that is inside the LED bulb.
  5. Press the small plastic tab on the back of the connector and pull it out of the LED bulb. Set the tail light assembly aside.
  6. Now the wiring for the taillight needs to be removed. Pull the wiring, and pry the rubber grommet inside the vehicle body out of its socket.
  7. Behind the rubber grommet, the wiring connects to a plug. Press the tab and pull the connectors apart.
  8. Take the new tail light and connect the tail light wiring to the vehicle’s wiring. Make sure it securely plugs in and clicks in place.
  9. Push the wiring back through the vehicle and insert the rubber grommet into the hole of the body. Make sure this grommet is flush around and sitting in its correct groove.
  10. Pins and a socket on the back of the taillight need to be aligned to the hardware on the body. Make sure the pins go in the holes, the socket goes over the retaining clip, and push the tail light into place.
  11. Insert the two screws and tighten them with the screwdriver. Make sure the brake light is now working. Repeat on the other side if necessary; you are all done!

I changed my brake light, but they still aren’t working. What’s wrong?

There are many causes of brake lights going out other than the bulb going bad. Make sure that the light is the problem and not something else by doing simple electrical checks. Start by simply checking the brake light fuse with this guide. Verify that the brake switch is functioning properly if the fuses are fine. Check the wiring for power to the lights as part of a deeper diagnosis.
