914lps Posted August 18, 2005 Share Posted August 18, 2005 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? Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted August 18, 2005 Share Posted August 18, 2005 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.

JimAt Posted August 18, 2005 Share Posted August 18, 2005 Also, while you are changing the bulbs every five years or so, it's a good idea to replace critical fuses: lights, radio, AC, etc. Quote Link to comment Share on other sites More sharing options...
914lps Posted August 18, 2005 Author Share Posted August 18, 2005 Thanks. I had it right. Remove the 4 screws and pull out the black plastric cover. Boy it was really stuck in there. Had to make a small pry bar with a screw driver! Quote Link to comment Share on other sites More sharing options...
gazhalim Posted September 16, 2005 Share Posted September 16, 2005 I realize that this is an old thread, but just wanted to see what type of bulbs you used. Can I just go to Autozone and tell them that I have a 91 LS 400 and they can look up the bulbs for me? Quote Link to comment Share on other sites More sharing options...
