my drivers side rear brake light is out. anything i should be wary of before i tear into it? also, does anyone think its just a bulb or maybe a fuse? thanks!!! oh yeah, its a 02 disco series II

 

You may want to jump in and replace some tail lights and don't worry too much about it, they do burn out. A good practice is to replace any bulb in sets of 2's as needed, if you see other bulbs that are starting to darken replace them at the same time.
