Overview

The Jabsco 18753-0178 is a replacement sealed-beam bulb kit for the Jabsco 135SL remote control searchlight. It matches the 50 watt 3-1/2 inch x 6 inch halogen beam used in the 60020 series, so it is the service part to order when the original lamp has failed or the light output has dropped.

This bulb kit is used in both 12V and 24V versions of the 135SL. That makes fit straightforward to verify on board: check that your existing light is a Jabsco 135SL in the 60020 series, then replace the lamp inside the light head rather than changing the full searchlight, control, or housing.

Key features

• Replacement bulb kit for Jabsco 135SL remote control searchlights in the 60020 series
• 50 watt sealed-beam halogen lamp in the 3-1/2 inch x 6 inch format used by the original light
• Compatible with 12V and 24V 135SL searchlight versions
• Uses the existing light-head wiring with spade-terminal connections during installation
• Made as a service part for restoring beam output without replacing the full searchlight assembly

Installation and fit

For a correct fit, confirm the searchlight itself is the 135SL. Bulb replacement is done at the light head by removing the retaining bezel, pulling the bulb assembly forward, disconnecting the spade terminals, then reconnecting the new bulb and reinstalling the bezel and screws. This is a straightforward service job for owners who are refreshing an existing searchlight system.

Because this is the lamp unit only, it is a good match for boats that already have the 135SL installed and need to bring the searchlight back into service without replacing the base, motors, or control panel.

Use on board

This part suits owners maintaining an existing searchlight for night approaches, marker identification, docking, or general spotlight use from the helm. On a working boat, cruiser, or sportfishing setup, replacing a tired beam can matter more than cosmetics, especially when the rest of the searchlight still moves and operates as it should.
