please helpI have a 91 arcua legend,i need to change my back brake light on the driver side,how do i do that.?Go to the auto parts store and buy the correct corresponding bulb. You will need to get at the back of the housing from inside the trunk. Most of the time you will need to pull out some of the inner lining. If you can see the back of the bulb after pulling back the trunk lining, then twist the housing counter clockwise to pull it out. Remove the old bulb. Make sure on the new bulb that you dont get finger prints or oil on it. It can result in premature burnout. Use a towel of some sort to put the new bulb in.
