Not sure but I believe you want to know how to change the bulbs? it its the front open you hood and look and you should see where the bulb is connected this is difficult on a 92 twist off the cap and remove bulb put new bulb back in flat side up make sure you even have to replace the bulbs it could be the connection. if it rear the bulb is located in the trunk and is pretty easy to figure out you just disconect the old bulb and replace it with a new one if after doing this and checking all your connections it still doesnt work then it gets more complicated because that is a sure sign it is a fuse problem however your car should have come with a manual if it didnt pick one up at your local auto store and it will tell you what fuse you need to replace..if you want to you can email me at xunderthexstarsx@aol.com
