Start vehicle and turn on turn signal and take a look. If the particular bulb you're trying to isolate is burnt out, turn on the opposite direction (side) and see where its located on that side...which should indicate where it is on the other side. If you have a bad bulb, see sources and related links below.

94 Buick Lesabre replaced battery and alternator and the alternator is not charging the battery. Battery light is on and off. Is this fusable link. If so where is it located
Hey Phill=the front ones can be gotten to from the rear of the light assy and on some of the cars you can get to the rear ones in the trunk. GoodluckJoe
If the signal light fuse is blown all the signal lights front and rear would not work. If you have one signal light out I would first suspect a bad bulb or bad connection.
is it in the rear spoiler? Thru the trunk, light socket is right below rear window

The socket size for the trunk tail light on a 2001 Buick LeSabre is 7mm. Bulbs can be purchased at most local automotive repair stores.
Up under the dash over the steering wheel left side. The upper one is the turn signals and lower one is for the flashers.
I think the light assembly screws out from the inside of the trunk.
there could be a bad ground for the lights, or there is a short somewhere between your fuse panel and your light
