Buying Guide: Light Board Purchase Considerations
- Trailer width compatibility: Ensure lights accommodate your trailer’s overall width and mounting pattern.
- Waterproofing and sealing: Look for IP ratings (IP65+ for lights, IP67/IP68 for submersible options) and gasketed housings.
- LED brightness and visibility: Higher lumens improve daytime visibility and safety at night or in poor weather.
- Wiring and installation ease: Prefer two-wire or simple harness options with clear color-coding to minimize wiring errors.
- DOT/FMVS108 compliance: For highway use, DOT-compliant lighting reduces liability and ensures standardized signaling.
- All-in-one vs. modular: Kits save time; individual lights offer custom configurations for unique trailer shapes.
- Durability: Steel or corrosion-resistant housings and waterproof seals extend service life in harsh environments.
- Warranty and replacement parts: Check availability of replacement lenses, gaskets, and bulbs when needed.
FAQ
- What is the difference between marker lights and tail lights?
Marker lights define the trailer’s edges; tail lights provide brake, turn, and running signals. - Are submersible trailer lights always necessary?
Not always, but submersible lights are highly recommended for boat trailers and vehicles exposed to water or mud. - Do LED trailer lights require special wiring?
Most LED kits use simple two-wire connections or standard harnesses; follow manufacturer instructions for polarity. - What is FMVSS108 compliance and why does it matter?
It is a U.S. standard ensuring visibility and safety for vehicle lighting on public roads. - Can I replace only damaged lights or do I need a full kit?
You can replace individual lights if your trailer is compatible; a full kit is convenient for major updates. - How do I choose between LED and incandescent trailer lights?
LEDs offer longer life, brighter illumination, and lower power draw, making them generally preferable for trailers.
