Imtra B15d to G4 Socket Adapter, Bi-Pin, Swivel

Overview

The Imtra ILBA1142-G4 is a lighting socket adapter that converts a B15d double-contact bayonet socket to a G4 bi-pin connection. It allows compatible G4 LED replacement bulbs to be installed in existing marine light fixtures without changing the original socket.

The adapter features a swiveling G4 connection that allows side-pin bulbs to be rotated into the appropriate position regardless of the orientation of the existing bayonet socket. This is particularly useful when converting boat lighting fixtures to G4 LED bulbs that require directional alignment.

Key features

• Converts B15d double-contact bayonet sockets to G4 bi-pin connections.

• Compatible with existing #1142 double-contact socket configurations.

• Swiveling connection allows directional alignment of side-pin G4 bulbs.

• Supports G4 LED bulb conversions in compatible marine lighting fixtures.

• Retains the existing bayonet socket during bulb conversion.

Compatibility and installation

The adapter is intended for fixtures equipped with B15d double-contact bayonet sockets. Confirm the existing socket type, available fixture clearance, and electrical requirements of the selected G4 bulb before installation. The adapter changes the bulb connection format but does not convert the fixture's supply voltage.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
