Today I did the interior lights LED change-out. Man, those tiny yellow bulbs get hot, hot, hot!! I bought the 08 and Up Subaru Impreza 5 Door Kit
and it works perfectly.
It comes with 6-bulbs..and no instructions really on which ones go where. The 3 bulbs with the sort of pointy ends on both ends are for the front two map lights and the center dome light. The two pillar type lights are for the license plate lights and the last bulb is for the trunk/boot light.
Just use a very tiny flat head screwdriver to pry the plastic covers from the map and dome lights and the covers will pop right off. I know..it's scary because I don't want to crack one of those covers either, but they really do just pop right off. The bulbs that go in the map and dome fixtures are slightly larger, so the tabs that hold the light will bend slightly further out..but that isn't any problem. Turn the light on when you hold the bulb up to the contacts to make sure you are putting it in correctly. It should light up as soon as you hit the contacts, if not, reverse the bulb since they are polarity fixed.
As others have noted, the license plate lights require a little bit of oomph to get them out. Mine require a good press on the side of the light toward the center of the car to shift them about 1/2" inward, then they just pull out and down. No problems at all getting them back in..
All of the LEDs look great. A nice cool white light that I don't feel is overpowering at all and gives a bit more of a modern look to the interior.
Nice, cheap, easy upgrade..
