How to Replace Cabin Light Bulb on a Mitsubishi Outlander

In this guide, we will show you how to replace the cabin light bulb on a 2019 Mitsubishi Outlander.

However, because it is so similar for many other models and even makes, this process can likely be repeated. We will also discuss how to find the right bulb size and wattage. 

What you will need

Tools

  • Flathead screwdriver 
  • or a plastic pry tool

Parts

  • Cabin light bulb part number: DE3175

Consumables

  • Gloves

Procedure

  1. First, insert a small flat head screwdriver into one of the corners closer to the center of the cabin light assembly.
  2. Pry from the corner carefully, be gentle and do not force the plastic, and do not scar the housing either. Pop the clear plastic cover from the assembly.
  3. Now, the light bulb can be pulled out; make sure to use a pair of gloves while handling light bulbs. Pull the bulb straight down and out of the socket. Touching the thin glass of bulbs can contaminate the surface with oils from your hands and lead to hot spots and premature failure of the bulb.
  4. With your new bulb in hand, make sure it is the same size and wattage; this bulb happens to be an eight-watt bulb; if you would like a bit brighter, you could go to a ten-watt or LED bulb.
  5. Insert the new bulb into its socket; it can be flipped either way if it is a regular filament type bulb. However, if it is an LED, it will only work one way because the positive and negative leads need to be connected to the correct sides, a test which way is correct by inserting it and turning the light on, flip the bulb if it does not turn on.
  6. Replace the clear plastic by aligning the sockets of the cover into place with the prongs sticking out of the trim and pressing it into place until it snaps in.
  7. Repeat this process on the other side, make sure to test the are working, you are all done!

Common causes of cabin light bulbs not working:

  • loose connections in the cabin light assembly
  • blown bulb
  • blown fuses or high resistance in the wiring of the light
  • an open or short in the electrical wiring

Do I need to replace both bulbs?

It is a good idea to replace both bulbs, even if the other is still working, the filaments in bulbs tend to wear out overuse and age, and they become dim. You can always save the old bulb as well for a backup!

How do I find what size and type of bulb I need?

Often times the bulb will be stamped with its part number on the metal housing. Alternatively you it is a good idea to search the make model and year of your vehicle on the internet and find its corresponding bulb part number. Parts shops can also look it up for you and will have catalogs in-store to also look it up yourself!
