Buying Guide: Key Considerations For Boat Trailer Marker Lights
- Waterproofing and environmental rating: For boat trailers, select lights with IP68 or IP69K ratings for submersion and saltwater exposure.
- Mounting style: Choose stud-mounted for quick installs, surface-mount for durable mounting, or bezel-friendly designs that minimize wiring.
- LED quality and brightness: Higher lumen output and wider angles improve visibility and safety on road and water.
- Electrical compatibility: Confirm the voltage (commonly 12V) and polarity and ensure compatibility with your trailer wiring harness.
- Durability and materials: Look for corrosion-resistant bases, stainless-steel hardware, and UV-stable lenses for longevity.
- Compliance: If DOT FMVSS-108 or SAE standards matter in your use case, verify certifications stated by the seller.
- Installation considerations: Some models offer ground-through-bezel design to reduce wiring time; others may require silicone sealant for IP67/68 protection.
