You want to change the tail light bulb?

The process for replacing tail light bulbs is the same in all models. If you have a burnt-out tail light bulb, you may need to replace the brake light, the reverse light or the turn signal. The procedure to replace each of the bulbs is the same.

Instructions

1. Open the Hummer's rear swing gate. This will expose the edge of the vehicle's tail light assembly. You'll see two small Phillips head screws that hold the tail light assembly in place. Put on your gloves.


2. Remove the two screws from the tail light assembly. Pull the tail light out and inspect the back for two bulbs. The top bulb is the brake light and turn signal. The bottom bulb is the reverse bulb. Determine which bulb you need to replace.

3Rotate the bulb's socket counterclockwise to disconnect it. Unplug the bulb from its socket.

4Push the replacement bulb into its socket firmly. Insert the socket back into the tail light. Turn it clockwise to secure it in place.

5Place the tail light into its cradle. Hold it with one hand and replace the Phillips head screws with the other.

You need to squeeze the little 'fingers' on that white piece to allow the taillamp assembly to be removed. See the YouTube video at the link.
How to remove tail lights in Dodge Avenger 2011 up

you will need to open the trunk and remove the carpet covering the inside where the tail lights are, find 2 or 3 nuts which are probably 8 or 10 mm,so use a socket and ratchet,remove the nuts and pull the tail light asembly out from the back and you will find the tail light bulb sockets. release the little latch/lock clips while turning the socket assembly about 1/4 turn counter clockwise and you can check each bulb. watch where the wire harness for each socket and also the tail light assembly is so you dont pinch or damage the wires when putting the tail light assembly back in. your owners manual may also give you these instructions and will tell you the correct bulbs to use for tail, brake and turn signal lights.

Rear Turn Signal, Brake, & Marker Lights

1. Disconnect the negative battery cable.
   
2. Open the trunk.
   
3. Unfasten the nuts or other retainers from the rear trim.
   
4. Unfasten or release the housing cover retainers.

On some vehicles, such as this 1986 Grand Am, you must remove the rear body panel with the lamp

Depending upon vehicle application, remove the lamp socket either by rotating it counterclockwise (approximately 1/4 turn) until the plastic tabs disengage, or by squeezing the metal tangs while pulling the socket from the light assembly


Remove the lamp socket assembly by turning it counterclockwise, then pulling it out

Generally, side marker lamps use small bulbs with flat, blade-type bases, and tail lights/turn signals use larger, round-based ("bayonet") bulbs.

1. Remove the bulb from the socket using the appropriate method. Bulbs with blade-type bases pull straight out, while those with round bases and protruding pins (bayonet-type bulbs) must be depressed, then rotated counterclockwise (approximately 1/8 turn) before pulling out.
   

Remove the side marker bulb from its socket by pulling straight out

To install:

1. Secure the bulb in the socket using the appropriate method. Bulbs with blade-type bases push straight in, while those with round bases and protruding pins (bayonet-type bulbs) must be inserted, then depressed and rotated clockwise (approximately 1/8 turn).
   
2. Install the lamp socket using the appropriate method. Depending on the type of socket, either engage the plastic tabs, and rotate the socket clockwise (approximately 1/4 turn), or push on the socket until the metal tangs engage.
   
3. Install the housing cover nuts.
   
4. If removed, install the rear fascia and light assembly.
   
5. Install the rear trim.

Look inside the trunk -- you may have to move the liner aside -- there are three plastic wing nuts holding in each tail light assembly. Remove the nuts and the entire assembly will come out. The light sockets come out with a quarter turn twist.

Remove trim panel inside trunk. A plastic nut retains tail light assembly in body. Remove the bolt, slide whole tail light from body, disconnect the wires, twist bulb socket to access bulbs.

remove the trim panel at the very rear of trunk, remove it and place it out of the way, remove tail light Assembly retaining nuts top and bottom, I think there are 6 per side, pull the tail light assembly straight back to access the bulbs for replacement.
