Buying Guide

What should I consider when choosing LED marker lights?

  • Voltage compatibility: Most 12VDC systems are standard for trailers and trucks; some models support 24V. Match your vehicle’s electrical system.
  • Waterproofing rating: For exterior mounting, IP68 provides full submersion resistance; IP65 offers splash resistance. Choose based on exposure.
  • Light color and purpose: Amber is commonly used for side markers and indicators; red for rear lighting or identification. Ensure color consistency with vehicle requirements.
  • Mounting style: Surface-mount with rubber grommets is easy to install; grommet-based or plug-and-play options reduce wiring work.
  • Lumen output and longevity: Higher lumens improve visibility at night; long lifespans (100k+ hours) reduce maintenance needs.
  • Durability: Plastic PC lenses vs. metal housings affect impact resistance and environmental tolerance.
  • Wiring: Note polarity (positive/negative) and wire length. Some sets include longer leads or simple two-wire designs.

How do these markers compare for different vehicle types?

  • Trailers and utility trailers: Look for IP68 waterproofing, 12V operation, and 60+ lumens per light for clear visibility.
  • Trucks and buses: Favor larger packs, higher durability, and universal voltage support for fleet applications.
  • Marine use: Prioritize waterproof seals and color variants that meet signaling conventions, with careful attention to corrosion resistance.
  • RV and caravan: Choose lights with robust grommets and reliable long-life LEDs to minimize maintenance on long trips.
