4Pcs 4 Inch Round LED Trailer Tail Lights (Partswcgg)
This set includes four 4-inch round LED tail lights with red and white configurations, grommets, and 3-prong pigtails for a complete installation. Each light houses 24 LED chips for bright output while drawing less power than incandescent fixtures. The units are IP65-rated for water and dust resistance, making them suitable for exposed trailer environments. Installation notes emphasize the ground wire as white, with red as high brightness and black for low brightness, and the option to drill holes to fit standard 3-prong plugs.
Consider the balance between brightness and ease of install. The compact 4-inch size keeps wiring neat on box trucks, while the included rubber grommets help seal the mounting area against the elements. Potential buyers should verify hole spacing and ensure compatibility with existing harnesses when upgrading from incandescent lights to LED units.
Nilight TL-01 6″ Oval Red LED Tail Lights (2-Pack)
Nilight’s TL-01 lights deliver 10 SMD LEDs per unit to provide a bright, red signal for stop/turn and tail functions, with a separate white LED array for reverse illumination. The design includes grommets for surface mounting and a 3-prong waterproof plug for straightforward wiring. The oval 6-inch form factor is a common fit for many trailers and box trucks, and Nilight emphasizes shake-proof mounting with enhanced grommet design to resist loosening over time. Installation is user-friendly for fleets replacing older lighting with LED tech.
Drivers should assess visibility in day-to-day conditions and ensure proper sealing around grommets to maintain IP65-rated protection. The two-pack makes it an economical choice for upfits that require matching pair replacements across multiple locations on a vehicle or trailer.
PIT66 Trailer Lights Kit With 6″ Oval Tail Lights
PIT66’s steel box tail light kit focuses on steel robustness with black powder-coated finish and pre-cut holes for 6″ oval tail lights and 2″ round side marker lights. The kit’s design emphasizes back-to-frame protection and weather resilience, backed by high-quality SMD LEDs for strong stop/turn signals and distinct tail marker illumination. Its sturdy construction suits heavy-duty trailer installations where galvanized or painted frames require durable mounting points. Wiring and bracket customization may be necessary to align with existing trailer harnesses.
For fleet operators, this kit provides a reliable foundation for upfit projects where a steel housing is preferred for impact resistance and longevity. The pre-cut holes simplify alignment, though some drilling and wiring work is still expected during installation.
Partsam 2x Red 6″ x 2″ Side Marker Lights
Partsam offers a 2-pack of sealed 6″ x 2″ red side marker and tail lights designed for robust exterior use. These 12V DC units feature 11 forward-facing LEDs plus a single LED at each end for enhanced side visibility. The reflective design boosts conspicuity for trailer sides, and the surface-mount layout with 4.8-inch hole spacing supports practical retrofits on many box trucks and trailers. The lights are designed to work in conjunction with standard trailer wiring harnesses, and the included hardware supports straightforward mounting.
When selecting, owners should weigh reflector performance against overall brightness and the ease of integration with existing marker lighting. The 11+1 LED pattern helps achieve side visibility without overshadowing rear signal functions, making them a balanced choice for upfit projects that require side accent lighting in addition to tail signals.
G-PLUS LED Trailer Steel Box Kit (6″ Oval Tail Lights)
G-PLUS presents a durable steel box kit that includes 6″ oval tail lights and 2″ marker lamps.

Boao’s dual 4-inch round tail light boxes come in a stainless steel housing with no coating, designed for durable trailer lighting upgrades. Each box emphasizes full welding for excellent sealing against moisture and weather exposure. The product includes two boxes, making it suitable for two-light retrofits or spares. Note that there are no pre-drilled holes, so installation requires custom drilling and wiring. The heavy 14-gauge stainless steel construction aims to withstand harsh working environments.
For operators performing upfits to older trailers or boxes, Boao provides a sturdy, drill-ready solution. The emphasis on sealing and corrosion resistance makes these a strong choice where long-term durability is a priority, particularly in challenging climates or frequent exposure to moisture.
Buying Guide: Key Purchase Considerations For Box Truck Tail Lights
- Compatibility: Check 12V systems, mounting patterns (3-stud, 6″ oval, 4″ round), and whether the unit fits your trailer or box truck’s existing harnesses and frame openings.
- Functionality: Look for multi-function units that combine stop, tail, turn, and reverse illumination. Some models also include license plate lighting for full compliance.
- Durability: Prioritize corrosion-resistant housings (ABS or stainless steel) and shatterproof lenses. Consider IP ratings (IP65 or higher) for weatherproofing.
- Ease of installation: Consider grommet mounting, pre-drilled holes, and whether the kit includes wiring pigtails, screws, and sealing gaskets. Simpler installs reduce downtime.
- Brightness and visibility: LED units typically offer higher brightness, longer life, and faster response times than incandescent equivalents. More LEDs can improve daytime visibility, but ensure electrical load is compatible with your system.
- Compliance and safety: Confirm DOT and SAE compliance to meet U.S. road standards and to pass inspections. This reduces the risk of fines and ensures consistent signaling for other drivers.
- Maintenance and availability: LED modules tend to be more reliable over time; however, ensure replacement parts are readily available for future servicing.
- Installation environment: If the trailer operates in salt environments or heavy rain, prioritize sealed units and corrosion-resistant hardware to extend life and reduce maintenance.
In selecting the best option, weigh fleet needs against installation complexity and total cost of ownership. For fleets prioritizing quick upgrades and universal fit, multi-function LEDs with robust housings are favorable. For specialized trailers or demanding climates, steel-enclosed or stainless options offer enhanced durability. Always verify compatibility with your vehicle’s wiring and frame specifications before purchasing to ensure a smooth retrofit.
