1996-1998 Buick Skylark Trunk Tail Light: Standard vs. Blackout Gran Sport
This guide covers common failures, inspection tips for used parts, and how to ensure you get the right trunk-mounted lamp for your 1996-1998 Skylark.
- This tail light is for the trunk lid ONLY and does not fit the vehicle's corners.
- For 1996-1997 models, this part does NOT fit the Gran Sport (GS) trim, which uses a distinct 'blackout' style tail light.
- When buying a used part, the most important checks are for cracks, the condition of the water-sealing gasket, and corrosion in the bulb sockets.
- Replacement is a simple DIY job requiring only basic tools and about 20 minutes.
Key Compatibility Warnings
Before purchasing a replacement tail light for a 1996-1998 Buick Skylark, be aware of two critical fitment details. Failure to verify these can result in buying the wrong part.
Warning: This specific tail light assembly, OEM part number 5978097, is designed to fit on the trunk lid only. It is often called the 'inner' tail light. It will NOT fit the outer corners of the vehicle on the quarter panels.
Warning: For model years 1996-1997, this standard tail light will NOT fit the Gran Sport (GS) trim level. The Gran Sport model was equipped with special 'blackout' tail lamps which have a darker, smoked appearance. While they mount in the same location, they are cosmetically different and are not interchangeable with the standard red tail lights.
Symptoms of a Failing Tail Light
Tail light failures can range from a simple burnt-out bulb to a damaged housing that requires complete replacement. Here are the most common symptoms:
- Cracked or Broken Lens: Physical damage from impacts is a common reason for replacement. Even a small crack can allow water to enter the housing.
- Condensation or Water Inside the Lens: Often called the 'fishbowl effect,' moisture inside the tail light is a clear sign that the seal has failed. 🎬 Watch: How to solve moisture and condensation in your tail lights. This water will cause corrosion on bulb sockets and electrical connectors, leading to frequent bulb burnouts and flickering lights.
- Dim, Flickering, or Inoperative Lights: While this can be a burnt-out bulb, it often points to a corroded bulb socket or a bad ground connection, frequently caused by long-term moisture exposure. A visual inspection of the socket for white or green powder is necessary.
- Faded or Hazy Lens: Over time, the sun's UV rays can cause the red plastic lens to fade to pink or become cloudy. This reduces the light output, making your vehicle harder to see and creating a safety risk. 🎬 See this guide on how to polish hazy tail light lenses.
Buying a Used 1996-1998 Skylark Tail Light
Since new OEM and aftermarket housings are generally no longer available, a used OEM part is the most practical option. Used OEM parts offer the original fit and quality, but a careful inspection is crucial.
What to Check Before You Buy
- Confirm the Style: First, ensure you are not buying a 'blackout' Gran Sport lamp for your standard 1996-1997 Skylark, or vice-versa.
- Inspect the Lens Surface: Look for deep cracks, chips, or scuffs. Minor surface scratches can often be polished out, but deep cracks compromise the housing.
- Check for Water Intrusion: Look for a 'water line' or dried mineral deposits on the inside of the lens. This indicates a past or present leak.
- Examine the Mounting Points: The light attaches to the trunk with several threaded studs. Ensure these studs are intact and not broken off. Check the plastic housing around the studs for stress cracks.
- Inspect the Bulb Sockets: If the wiring harness and sockets are included, twist them out and look at the metal contacts. They should be shiny and free of green or white corrosion. A corroded socket is a major red flag and will cause persistent electrical issues.
- Check the Gasket: The tail light seals against the trunk with a foam or rubber gasket. Make sure this gasket is present, complete, and still soft. A brittle or missing gasket will lead to water leaking into your trunk.
Replacement Overview
Replacing the trunk-lid tail light on a 1996-1998 Skylark is a very simple DIY job suitable for any skill level.
- Difficulty: 1 out of 5
- Estimated Time: 15-20 minutes
- Tools Needed: Ratchet with a small socket (likely 8mm or 10mm), trim removal tool (or flathead screwdriver).
Basic Steps
- Open the trunk.
- Remove the fabric trunk liner from the back of the trunk lid to access the rear of the tail light. It is usually held on by a few plastic clips. 🎬 Watch: A quick walkthrough on replacing your Buick Skylark bulbs.
- Disconnect the main electrical connector going to the tail light assembly.
- Locate and remove the nuts (typically 3 or 4) holding the tail light studs.
- Carefully push the tail light out from the back.
- Installation is the reverse of removal. Hand-tighten the nuts first to avoid cross-threading, then snug them down gently. Do not overtighten, as this can crack the plastic housing.
Known Issues, Recalls, and Service Bulletins
There are no recalls or Technical Service Bulletins (TSBs) issued by the NHTSA specifically for the tail light housings on the 1996-1998 Buick Skylark. Any functional issues are typically related to normal wear and tear, such as bulb failure, corrosion, or physical damage.

| Shop Labor | $40 - $75 | Typically a 0.3-0.5 hour job at a professional repair shop. |
Frequently Asked Questions (FAQ)
Is this the same as the tail light on the corner of the car?
No. This part (5978097) is for the trunk lid only. The lights on the outer corners (on the quarter panels) are a different part number and shape.
Will this tail light fit my 1997 Gran Sport?
No. The 1996-1997 Gran Sport models used a special 'blackout' style tail light with a darker, smoked lens. This standard red lens tail light is not the correct part for that trim.
My tail lights keep burning out. Is the housing the problem?
It's very likely. Premature bulb failure is most often caused by either vibration or moisture. Check the tail light housing for cracks or a bad gasket that is letting water in, which then corrodes the bulb socket and causes electrical problems.
Can I just polish my faded tail light instead of replacing it?
Yes, you can use a plastic polishing kit to temporarily restore some clarity and color to a faded or hazy lens. However, this is usually a temporary fix, as the original protective UV coating has worn away. The fading will likely return within a few months.
