Check Price on Amazon

Best for: Buyers who need a multi-function 12V light pair for trucks, trailers, RVs, vans, boats, or flatbeds. The listing describes stop, turn, tail, reverse, and license-plate illumination, making this a versatile option across several vehicle types.

Its features specify PMMA lenses, a rugged ABS housing, sonic-welded construction, and stainless steel front screws. The feature details enumerate 16 red LEDs for stop, turn, and tail functions, 18 white reverse LEDs, and four white license-plate LEDs per light. Those details total 38 LEDs, despite “28 LED” in the product name.

Why it was selected: It combines several rear-light functions with materials described as UV resistant and corrosion resistant. Limitation: Wrangler YJ/CJ installations may need modification, and buyers should confirm the light’s size and wiring suit their application.

Partsam Submersible Square Trailer Lights

Best for: Trailer and boat owners who want a submersible square light set with marker and reflector functions. The listing identifies an IP68 rating and describes applications including trailers under 80 inches, trucks, buses, tractors, and boats.

The curb-side light has 15 red diodes and provides stop, turn, tail, rear-reflector, side-marker, and side-reflector functions. The street-side light adds four white diodes for license-plate illumination and is listed with seven functions. The two sides therefore differ; check which unit goes on each side before installation.

Why it was selected: Its stated submersible design and multiple safety functions make it a useful comparison for marine and trailer applications. Limitation: The lights have side-specific features, so they are not identical replacements. Verify the supplied configuration and wiring against your setup.

Partsam 16 LED Red And White Pair

Check Price on Amazon

Best for: Owners planning a DIY replacement on a 12V truck, trailer, SUV, RV, van, boat, or Jeep project. The listed functions include stop, turn, tail, backup, and reflectors, which cover common rear-light needs.

The product is supplied as two red-and-white lights. Its description calls the lights universal, but specifically says Jeep YJ, JK, CJ, CJ-7, and CJ-5 applications may require modification and that these are not factory Jeep lights.

Why it was selected: This pair offers backup lighting as well as stop, turn, and tail functions, making it a practical choice when reverse illumination is important. Limitation: A license-plate light is not included. Buyers should plan for that separately if their vehicle requires one and should allow for possible DIY fitting work.

Partsam 39 LED Stud Lights

Best for: Buyers seeking a square 12V pair with separate LED groups for rear signaling, reverse lighting, and license-plate illumination. Each light is listed with 39 LEDs: 12 red for stop, turn, and tail; 21 white for reverse; and six white for the license plate.

The product is described as hardwired, impact resistant, and water-tight sealed, with each LED directly wired. Its stated applications include trucks, trailers, boats, buses, and vans.

Why it was selected: The feature breakdown makes its functions easy to compare, and the reverse and license-plate illumination are built into the described setup. Limitation: Jeep YJ, JK, and CJ-family installations may require DIY modification; the listing says these are not factory Jeep lights. Confirm mounting and wiring before purchase.

Partsam Square Trailer Light Kit With Boxes

Partsam square LED trailer light kit with steel mounting boxes

Best for: Trailer owners who want a kit that includes steel mounting boxes and a license bracket. The product name describes it as a waterproof square LED trailer light kit for trailers under 80 inches, boats, and trucks, and lists IP68 and DOT approval.

Why it was selected: The included mounting hardware may suit buyers who need more than replacement lamps alone. The name also identifies red LED stop, turn, tail, license, brake, and running-light functions.

Limitation: The supplied product details do not specify LED count, wiring, or the exact functions of each lamp. Check the listing and compare the mounting-box dimensions and wiring with your trailer before choosing this kit.

Buying Guide: How To Choose Square LED Tail Lights

Which functions does your vehicle need?

Confirm whether you need only stop, turn, and tail signals or also reverse, side-marker, reflector, and license-plate illumination. Product descriptions vary: some include white reverse LEDs, while others provide a license-plate light on only one side or exclude it entirely.

Will the lights fit your mounting setup?

Compare the light’s shape and mounting method with the existing opening, screw locations, bracket, or mounting box. A universal label does not guarantee a direct fit. Jeep-oriented listings specifically warn that modifications may be necessary, so treat them as DIY options rather than automatic factory replacements.

Will the lights be exposed to water?

For boat trailers or other wet environments, look for a clearly stated water-resistance feature, such as the IP68 or submersible descriptions provided for selected Partsam products. Confirm that wiring connections and installation follow the product instructions; a light’s stated resistance does not establish that every part of an installation is waterproof.

What should you verify before ordering?

  • Confirm the vehicle uses a compatible 12V system where that requirement is stated.
  • Check whether the pair has left- and right-side-specific functions.
  • Verify wiring, mounting dimensions, and whether a license-plate lamp is included.
  • Compare the listing’s LED count and function details rather than relying only on the product name.

Frequently Asked Questions

Are square LED tail lights universal?

Some are described as universal for multiple 12V vehicle types, but fit is not guaranteed. Check dimensions, wiring, mounting, and vehicle-specific modification notes.

Do all square LED tail lights include reverse lights?

No. Some listed products include white reverse LEDs, while others focus on stop, turn, tail, marker, and license functions. Check the feature list for the exact functions.

Are these lights suitable for boat trailers?

Several products list boats or trailers as applications, and some describe submersible or waterproof construction. Verify the stated water-resistance details for the specific model.

Do these products include license-plate illumination?

Not all of them do. Some list white license-plate LEDs, one Partsam pair explicitly excludes a license-plate light, and another provides illumination on the driver-side unit.

Can I install square LED tail lights without modification?

That depends on the vehicle and mounting arrangement. The listings specifically warn that some Jeep YJ, JK, and CJ-family installations may need DIY modifications.
