Perko Clear Medium Prefocus Bulb, For Double Lens Navigation Lights, 24V, 55W

Overview

The Perko 0342024CLR is a 24V clear medium prefocus replacement bulb for Perko double lens navigation lights. It is rated at 55 watts and is used where the fixture is built around a medium prefocus socket and a 24V circuit.

This is the bulb to match when you are servicing a Perko navigation light that specifically calls for Cat. No. 0342024CLR. Using the same base style, voltage, and wattage matters in navigation lights because the lamp has to sit in the correct position inside the optic and run on the boat's existing 24V system.

Key features

• 24V, 55W replacement bulb for Perko navigation lights that specify 0342024CLR
• Clear lamp with a medium prefocus base for Perko double lens fixtures
• Made for fixtures that use a medium prefocus socket, which keeps the lamp aligned in the housing
• Useful for rebulbing a serviceable navigation light without replacing the full assembly

Compatibility and fit

This bulb is not a universal replacement. Before ordering, check the marking on the old lamp or the light's parts list and confirm three points: 24V supply, 55W rating, and a medium prefocus socket. That helps avoid buying a bulb that fits the opening but does not seat or focus correctly.

It suits boats running 24V navigation lighting where the fixture calls for this exact lamp, including Perko double lens navigation lights that use medium prefocus sockets. For 12V, 120V, 220V, rough service, or other base styles, use the lamp specified for that fixture instead.

Installation and service

For service work, shut off power, let the fixture cool, and replace the lamp with the same specification rather than swapping voltage or wattage. Seat the prefocus base fully, close the housing carefully, and test the light after reassembly so you can confirm the beam returns to normal before leaving the dock.

Use on board

This bulb is a good match for owners, captains, and technicians maintaining 24V Perko navigation lights rather than replacing the whole fixture. It fits routine maintenance on boats that already have the correct socket and need the light back in service with the proper lamp style.
