How to Replace the Tail Light in a Buick LeSabre

by Jody L. Campbell

The taillight/backup light/license plate light assembly is separate from the brake light/turn signal light assembly on the Buick LeSabre. No matter what rear bulb you have to replace, you must access the trunk area to do so. Although a modest investment, the amount of time and effort it takes to remove the assemblies, you should consider replacing all the lights once the unit is disassembled.

Step 1

Open the trunk of the Buick LeSabre.

Step 2

Locate 7 nuts underneath the trunk lid (3 on each end of the trunk lid and 1 in the middle). Remove each one using a nut driver.

Step 3

Manipulate the trunk lid at chest level and gently pull the rear taillight assembly slightly away from the trunk lid.

Step 4

Locate the burned out bulb sockets and then remove the bulbs. Insert the new bulbs into the socket and test by turning on the lights before reassembling.

Step 5

Replace the tail light assembly by aligning the studs inside the predrilled holes in the trunk lid. Refasten the 7 nuts.

Step 6

Remove the cargo net if applicable to replace the brake and/or turn signal light.

Step 7

Unscrew the plastic wingnut that the cargo net is attached to. Pull back the trunk liner.

Step 8

Remove the 2 plastic wingnuts under the trunk liner.

Step 9

Pull the brake light assembly outward from the back of the LeSabre.

Step 10

Locate the socket of the burned out bulb and then turn counter clockwise 1/4-inch to release it from the assembly.

Step 11

Remove the old bulb from the socket and replace with a new one. Test the light before reassembling.
