Overview

The Lopolight 400-405 is an adaptor plate for mounting a Lopolight Single 180 G2 navigation light to the boat. It is a mechanical mounting part, so it draws 0 mA at both 12 VDC and 24 VDC.

Use it when you need the correct mounting footprint between the light and the mounting surface, whether that is a flat panel, a mast bracket, or a custom pod. It helps the light sit square and stay tight when the boat is taking vibration and regular washdowns.

This is a good match for owners and builders installing a Single 180 G2 who want a clean mount without adding any electrical load or extra wiring to the circuit.

Key features

• Made for Lopolight Single 180 G2 navigation light installations
• 0 mA current draw at 12 VDC and 24 VDC (no added electrical load)
• Provides the correct mounting interface between the light and the mounting surface
• Purely mechanical accessory, no wiring or network integration required

Compatibility and fit

Fits the Lopolight Single 180 G2 navigation light. Confirm your light is the Single 180 G2 version before ordering, since other Lopolight models use different footprints and hardware.

Plan for enough clearance around the light body and cable exit once the adaptor plate is in place, especially on tight mast mounts, arches, and rail brackets.

Installation and setup

Dry-fit the plate and light first, then mark and drill the mounting holes to match your structure. On cored decks or hardtops, seal the core properly around fasteners so water cannot migrate into the laminate.

Bed the mating surface and fasteners with a marine sealant suited for your mounting material. If you are joining dissimilar metals, use an isolating barrier and anti-seize where appropriate to slow down galvanic corrosion in saltwater.

Maintenance and care

As part of routine navigation light checks, confirm the mount has not worked loose and that the bedding has not cracked. Re-bed the joint if you ever see movement, staining, or water intrusion around the mounting holes.
