Buying Guide
- Power and voltage: Verify that the light supports your boat’s 12V or 24V system. LED options typically consume less power than incandescent models.
- Mounting base: Decide between 2-pin or 3-pin bases. Some products provide bases that are only compatible with specific pole lights; confirm base compatibility before buying.
- Height and mounting: Consider the transom height and preferred visibility. Telescoping poles offer flexibility, but ensure the pole can be stably mounted on your boat’s stern.
- Visibility range: USCG-compliant lights commonly offer 2 NM or 3 NM visibility. Higher ranges improve safety in busy waterways but may require brighter LEDs and better heat management.
- Durability and weather sealing: Look for corrosion-resistant housings and waterproof ratings suitable for marine environments. A sealed design reduces moisture ingress and longevity concerns.
- Maintenance: Some models include extra bulbs or easy-to-replace LEDs. Plan for routine checks and bulb replacements to maintain peak performance.
