1. Preparation:
* Safety First: Park on a level surface, engage the parking brake, and turn off the vehicle. If possible, work in a well-lit area. Wear safety glasses.
* Gather Tools: You'll likely need a Phillips head screwdriver (possibly a small one) and maybe a trim tool (plastic pry tool or similar to avoid scratching the plastic).
2. Accessing the Light Assembly:
This is the trickiest part and depends on the specific light. Generally, you'll need to:
* Remove the access panel: The 1988 Chevy Celebrity typically has panels covering the rear lights that need to be removed. These are usually held in place by screws or clips. Carefully inspect the area around the light; you might find screws along the edge of the taillight assembly or inside the trunk. Start by gently prying around the edges of the panel with a trim tool, working your way around until it releases.
* Locate the light socket: Once the access panel is removed, you should see the bulb sockets within the light assembly.
3. Replacing the Bulb:
* Disconnect the connector: Gently disconnect the electrical connector from the back of the light socket. It usually just pulls straight off.
* Remove the bulb: Carefully twist the old bulb counterclockwise (usually) and pull it straight out.
* Install the new bulb: Insert the new bulb, making sure it's seated correctly. Tighten it by twisting clockwise. Ensure it's the correct type and wattage – check your owner's manual.
* Reconnect the connector: Reattach the electrical connector securely.
4. Reassembly:
* Replace the access panel: Carefully put the access panel back in place, making sure it's aligned correctly before securing it with the screws or clips.
Important Considerations:
* Owner's Manual: Your owner's manual should provide the most accurate and detailed instructions for changing your rear lights. Look for a section on maintenance or lighting.
* Bulb Type: Make sure you buy the correct replacement bulb. The owner's manual or the old bulb itself should indicate the bulb type (e.g., 1157, 3157). Auto parts stores can help you find the right one.
* If it's difficult: If you are having trouble removing the panel, take extra caution. Forcing it can break clips or damage the surrounding area. Consider consulting a repair manual or a professional mechanic if you are unsure.
Without knowing *which* light you need to change, this is the most general guidance I can offer. If you can specify (brake light, turn signal, etc.) and provide a picture, I might be able to offer more specific help.
