Partsam 12V Submersible Square LED Trailer Light, Red/White
Best for trailers under 80″ width requiring both curb and street side lighting. This Partsam unit provides two versions: a 6-function curb-side light (Stop, Turn, Tail, Rear Reflector, Side Marker, Side Reflector) and a 7-function street-side light with additional license plate illumination. It includes a mix of red and white LEDs for visibility and regulatory compliance. Use this when you need a versatile, color-balanced signal with license illumination on the driver’s side.
Who this is for: DIY trailer operators needing a reliable, multi-function light with plate illumination and a robust water seal for marine or RV use. Caution: As with dual-function sides, plan wiring to avoid accidental cross-connection between curb and street sides.
Nilight TL-01 6″ Oval LED Tail Lights (2-Pack)
Best for quick-install scenarios where surface mounting and plug connections are preferred. Each light hosts 10 high-brightness SMD LEDs, offering strong turn/brake signals and clear tail lighting. The included grommets and a 3-prong plug simplify mounting on diverse trailer types, including RVs and Jeeps. The compact oval design fits many standard mounting locations, and its shake-proof connections help prevent loosening on rough roads.
Who this is for: Users seeking a straightforward upgrade to bright, low-draw LED lights with an uncomplicated install. Caution: The smaller size may need precise hole alignment; ensure mounting compatibility before purchase.
MAXXHAUL 70205 Trailer Light Kit
Best all-in-one kit for trailer owners who want a complete lighting system with a dedicated wiring harness. This kit includes two LED stop/tail/turn lights, two amber clearance lights, a license plate bracket, and a wiring harness. The 22‑ft color-coded harness simplifies installation and provides a cohesive signal system across multiple trailer types. It delivers reliable LED performance with long life and better durability than incandescent setups.
Who this is for: People upgrading multiple trailers or replacing an entire lighting system at once. Caution: Verify the harness length and mounting space to ensure a clean, secure setup on larger trailers.
CZC AUTO 12V Left/Right Trailer Lights
Best for high-visibility, DOT-compliant lighting on under-80″ width trailers. These left/right lights provide six common functions plus a license plate light on the driver’s side, with a focus on water resistance due to sonic welding and tight seals. The design emphasizes reliability underwater and in wet environments, using 18-gauge copper wiring for stable performance.
Who this is for: Trailer operators prioritizing DOT compliance and enhanced waterproofing. Caution: Ensure careful edge sealing during installation to maximize water resistance over time.
Wellmax 12V LED Trailer Lights
Best for DOT-compliant, fully sealed, submersible tail lights. Wellmax focuses on corrosion-resistant construction and maximum visibility with bright LEDs. The kit includes two lights with stainless hardware for easy mounting and durable performance in harsh weather. Fully compliant with DOT FMVSS108 standards, helping reduce liability risks and improve regulatory peace of mind.
Who this is for: Owners seeking a rugged, compliant lighting solution with long-term durability. Caution: Confirm compatibility with your trailer’s mounting pattern to ensure a seamless fit.
Buying Guide
What should I consider when choosing LED trailer brake lights?
Trailer width, mounting style (surface mount vs. recessed), and whether you need a full kit or individual lights will guide your choice. If you tow in wet or marine environments, prioritize submersible and IP-rated lights. For regulatory compliance, DOT/FMVSS108 compliance is a major factor to avoid liability.
Do I need a full kit or individual lights?
Full kits simplify wiring and ensure consistent signal behavior across lights. Individual lights can work well for targeted replacements or adding lights to larger trailers as needed.
What about installation difficulty?
Surface-mount units with grommets are typically easier for quick upgrades. Wiring harnesses and license plate illumination add to setup complexity but improve functionality and aesthetics.
How important is waterproofing?
Very important for trailers exposed to rain, snow, or saltwater. Look for IP ratings like IP67 or IP68 and robust sealing methods (sonic welding, gluing, and gasket design) to minimize water ingress.
What about durability and reliability?
Choose lights with corrosion-resistant housings, strong mounting hardware, and stable electrical connections. LEDs generally offer longer life and lower power consumption than incandescent options.
What is the best choice for a specific towing scenario?
– Narrow trailers under 80″ wide: CZC AUTO or Partsam options with left/right configurations work well.
– Complete new setup: MAXXHAUL kit provides a full system with wiring and license plate bracket.
– Quick upgrade: Nilight’s oval lights offer fast, surface-mount installation with reliable LEDs.
Quick FAQ
- Are these lights waterproof? Most are rated IP67 or IP68, suitable for wet environments.
- Do they require a separate license plate light? Some models provide it on the driver’s side light; others require a separate plate light.
- Will they fit under 80″ trailers? Yes, several options are designed specifically for under-80″ widths.
- Do the lights come with a wiring harness? Some kits include harnesses; others are sold as individual lights.
- Do these comply with DOT standards? Many models claim DOT or FMVSS108 compliance; verify per product listing.
- Can I replace only one light at a time? Yes, most 12V LED trailer lights can be swapped individually, but a matched pair is ideal for color consistency.
