Q1: Will these bulbs fit my boat light fixture?

A: These bulbs are designed for standard 31mm / 1.25 inch festoon sockets. Please measure your original bulb length before purchasing. If your stock bulb is 31mm, these can be used as direct replacements.

Q2: What voltage do these marine LED bulbs work with?

A: These bulbs are designed for DC 12V systems. They are commonly used for boat anchor lights, masthead lights, stern lights, bow lights, all-round lights and running lights.

Q3: What should I do if the bulb does not light up after installation?

A: Please remove the bulb, flip it 180 degrees, and reinstall it. These LED festoon bulbs are polarity sensitive, so reversing the direction usually solves the issue.

Q4: Are these bulbs bright enough for boat navigation lights?

A: Yes. Each bulb uses 24 pieces of 3014 SMD LED chips and produces 6500K pure white light with up to 300 lumens. Please make sure your fixture and local boating requirements are compatible with LED replacement bulbs.

Q5: Is installation difficult? Do I need extra wiring?

A: No extra wiring or modification is needed. These are plug-and-play direct replacement bulbs. Simply remove the old 31mm festoon bulb and install the new LED bulb.
