Nilight 5” X 3” Rectangular Trailer Tail Light
The Nilight rectangular tail light uses 10 ultra-bright red SMD LEDs with two brightness levels. The high brightness setting serves as a stop/brake light, while the lower setting functions as a tail light, with lens design enhancing visibility to trailing vehicles. A distinctive anti-loosening design adds stability: ear-like side features and upgraded grommet notches help secure the unit and prevent detachment of the 3-prong plug. Flush-mount installation is straightforward with provided grommets, and the mount hole measures about 5.47” x 3.58” x 2.26”. This model is ideal for 12V systems on trucks, ATVs, UTVs, buses, RVs and campers requiring reliable, bright signaling.
6PCS 5×3 Inch 24 LED Stop/Turn/Tail Lights
This package includes six rectangular tail lights, each housing 24 LEDs with a reflective lens. The red units serve as stop/brake and tail lights, while the white units function as reverse lights. The lights employ a plug-and-play 3-prong harness and are designed for easy installation on trailers and trucks. Dimensions are around 5.1″ x 3.3″ x 1.0″ (light only); overall housing is roughly 6.4″ x 4.6″ x 1″. White ground wire, red high-brightness wire, and black low-brightness wire simplify wiring. IP65 waterproofing helps withstand weather exposure, though direct submersion is not recommended.
CZC AUTO 2PCS 12V Submersible Rectangular Lights
CZC AUTO offers a dual-lighting package featuring stop, running, turn signals, and license plate illumination in a sealed, submersible design. The IP68 rating indicates strong waterproof performance for marine and boat trailer use. The fins and seams are sealed with Sonic Welding; 18-gauge pure copper wiring supports reliable electrical performance. The LEDs are fully solid-state, with compliance to DOT standards and rigorous pre-shipment photometric testing. These lights are designed for boat trailers and marine-grade towing while maintaining visibility in all weather and water conditions.
Partsam 12V Submersible Rectangular Kit
Partsam’s 12V rectangular lights cover seven signaling functions: stop, tail, turn, side markers, and rear reflexes, plus a license plate light on the driver-side. Left and right lights house different diode counts (22 diodes on the left, 18 on the right) to distribute brightness and signaling. These waterproof modules use welded construction to seal out moisture and vibration, meeting DOT standards for trailers, trucks, and campers. Each light measures about 8.42″ x 3.27″ x 2.87″, suitable for mounting on trailers wider than 80 inches, with stainless steel mounting hardware for rugged use.
6Pcs Red 5″ x 3″ Rectangular LED Tail Light Kit
This kit contains six 3×5 LED tail lights designed for heavy-duty use on tow trucks, trailers, semi-trucks, and flatbeds. They are recessed-mount with rubber grommets and are compatible with standard 3-prong trailer wire pigtails. Each light is rated for 12V operation, with a Red lens featuring 12 LEDs for stop/turn/brake signaling and a White/Black wire setup for ground and tail functions. The housing is IP65-rated to resist sand, dust, dirt, rain, and snow, and the kit’s dimensions fit common trailer cutouts while maintaining a compact profile for easy installation.
Buying Guide: Key Considerations And Comparisons
- Waterproofing and submersion rating: For trailers exposed to water and splash, look for IP68 or IP67 ratings, and some models advertise submersible capability. Consider your environment—coastal, marine, or off-road use may demand higher sealing.
- Brightness and signaling modes: LEDs with multiple brightness levels (e.g., separate tail and brake brightness) provide clearer signaling to following drivers. Check whether the unit supports stop, tail, turn, and reverse functions in a single housing or as separate units.
- Mounting style and fit: Flush-mount designs offer a clean look but require precise hole sizing. Recessed or grommet-mounted options may require larger cutouts. Confirm hole dimensions and mounting hardware compatibility with your trailer or vehicle.
- Wiring and plug compatibility: Many lights use standard 3-prong plugs. Verify color codes (ground, high brightness, low brightness) and ensure wiring matches your trailer harness.
- Durability and build: Look for weather-resistant housings, corrosion-resistant materials, and gasketed seals. For marine use, stainless steel hardware adds longevity against saltwater exposure.
- DOT and standards compliance: Trailers and commercial vehicles in the U.S. may require DOT-compliant lighting. Check listed standards and independent testing to ensure legal compliance.
- Warranty and support: A robust warranty helps cover manufacturing defects or early wear. Consider brands offering responsive customer support and accessible spare parts.
When selecting rectangular LED tail lights, balance the total signaling coverage with installation ease and environmental exposure. For high-visibility needs on road-legal trailers and heavy-duty equipment, opting for higher-brightness LEDs, multi-function housings, and submersible ratings can reduce the need for frequent replacements and re-wiring.
