How do I replace a tail light in my BMW? Do I have to take it to the shop or can I do it myself?

well you are goin to need to know the bulb size and number, so to get to the burnt out bulb, go into the trunk directly behind the bulb. There should be hardened felt covering the back of the bulbs held in by plastic screws or plugs remove them and carfully fold back the felt. Now remove the light socket with the dead bulb by twisting it the pull out the light bulb. now go to your localauto store and ask the staff to help ou bind the matching bulb. buy it and install it.
