Buying Guide
Key purchase considerations help match lights to your trailer or boat needs. Consider the mounting style, waterproofing, light output, and compatibility with 12V systems. Decide between stud-mounted, surface-mounted, or combination options based on your trailer type and mounting space. Evaluate IP ratings (IP65, IP67, IP68) for exposure to water, salt, and humidity. Check the number of LEDs per light for brightness and the required signal color (red for rear, amber for side markers). Look for kit content, including mounting hardware, screws, and wire leads compatible with your wiring harness. Finally, verify DOT/FMVSS compliance when required by local regulations.
