Changing / Replacing License Plate Light


914lps

Recommended Posts

I know this has been covered but after playing with "search" for an hour. I'm posting this. On a 91 LS 400 how do you replace the license plate lights? Both of mine are out. I undid the screws :chairshot: on the outside, but nothing comes loose. Can't find an opening on the inside of trunk. Whats is the trick?

As many times as I changed these bulbs on my 90 LS over 13 1/2 years, you would think I would have the procedure exactly memorized.

I remember I had to remove the screws that hold the black plastic garnish to the trunk lid - the plastic panel above the license plate that extends all the way between the taillights - the license plate light lenses are part of this garnish. If I had not changed the bulbs in a few years, the black plastic garnish tended to get stuck and I had to gently pry it down with a well taped screwdriver blade. The plastic garnish is quite sturdy but still pry gently - it may be brittle after all these years.

Then I replaced the bulbs. I think the bulbs are the same as in the corner lights by the headlights.

Getting the screws back in were a little more difficult since the two bulb housings can move around a bit inside the trunk lid. I sometimes used a finishing nail to line up the holes.

I suggest changing all the exterior bulbs every five years or so even if they do not burn out. I replaced all my bulbs at about the 10 year mark and was surprised to find that the glass on some of the original bulbs were very blackened reducing light output.
