Partswcgg LED Square Rear Combination Tail Lights 2-Pack — 12V Brake/Turn/Backup with Side Markers

These universal 12V LED rear combination tail lamps from Partswcgg are designed to upgrade dim or damaged rear lamps on trailers, flatbeds, trucks and many other vehicles. Each kit includes two square assemblies that integrate multiple LED functions—brake/turn, tail/license, reverse, and side markers—plus mounting hardware. They are not a direct factory plug-and-play swap for every model and may require minor trimming, drilling, or splicing during installation.

How do these tail lights improve visibility behind my vehicle?

LEDs produce brighter, crisper light than many incandescent units, making brake, turn and reverse signals easier for following drivers to see. The Partswcgg assemblies group multiple LEDs per function to provide consistent illumination and faster response time.

• 16 LEDs for brake/parking/directional signals for strong rear signaling
• 21 white LEDs for a bright backup light field
• 6 LEDs dedicated to the license plate illumination
• 3 side-marker LEDs to enhance lateral visibility

What wiring and installation should I expect?

These housings are bolt-in replacements and typically require cutting the stock pigtail and splicing the vehicle wiring to the new unit’s leads. Wire color functions are provided, but they may differ from factory wiring, so verify each circuit before finalizing connections.

• White: ground
• Blue: reverse/backup light
• Black: tail/license plate/side marker circuit
• Red: stop/turn/brake circuit
• Resistors or load equalizers may be needed for vehicles with incandescent flash systems (not included)

Will these lights fit my vehicle without modifications?

These Partswcgg rear combination tail lights are made for broad compatibility with 12V systems but are not guaranteed to match factory mounting patterns on every model. Bolt hole spacing is approximately 2" and the assemblies are slightly larger than many stock lenses, so drilling or cosmetic trimming may be necessary for some installs.

• Approximate bolt spacing: 2 inches
• Removable lens for access during wiring and bulb/LED service
• May require redrilling, trimming, or spacer brackets for non-standard vehicles
• Not a direct factory swap for certain Jeep Wrangler YJ/CJ factory lights

What should I check before ordering to avoid surprises?

Confirm your vehicle runs on a 12V system, measure available mounting space, and compare existing connector/wire colors to the provided wiring map. If your vehicle uses incandescent lamps, plan for additional resistors or adapters to prevent hyper-flashing or error codes.

• Verify 12V electrical system compatibility
• Compare hole spacing and overall lens dimensions to your current light
• Prepare basic tools for splicing and mounting (drill, solder/crimp, sealant)
• Have resistors or a load equalizer on hand if needed

Who is this for: The Partswcgg 2-pack square LED rear combination lights suit vehicle owners, DIY mechanics, fleet operators and trailer owners who want a brighter, long-lasting LED upgrade and who are comfortable performing basic wiring splices and minor mounting modifications. They are ideal when improving rear visibility or replacing worn or nonfunctional rear lamps on trucks, trailers and other 12V platforms that accept a bolt-in assembly.
