Overview

The Lopolight 400-401-B is a circular aluminum baseplate for Lopolight horizontal-mount navigation lights, finished in black. It measures 130 mm across and weighs about 11.99 oz (0.34 kg), so it adds a solid footprint without adding much weight up high.

This is a replacement baseplate meant for repairs and refits where the original baseplate is worn, damaged, or you want a clean mounting surface again. The light itself is not included.

Key features
  • Circular 130 mm baseplate for Lopolight horizontal-mounted navigation lights
  • Aluminum construction with a black finish for a tidy look on a cabin top, hardtop, or radar arch
  • Can be used with Lopolight bases 400-034, 400-035, and 400-037
  • No wiring or voltage considerations since it is a mechanical mounting accessory
  • Lightweight at about 11.99 oz (0.34 kg) for easier handling during installation
Compatibility and fit

This baseplate is intended for Lopolight horizontal mounted lights. Before drilling or sealing anything, confirm you have enough flat surface area for a 130 mm base and that the mounting holes line up with your existing light base and cable routing.

Installation and setup

Installation is a straightforward swap: remove the light and old baseplate (if installed), clean the mounting surface, position the new baseplate, then fasten it down evenly. Any deck or hardtop penetrations should be sealed appropriately for your mounting location to keep water out of the core.

Materials and corrosion resistance

Aluminum hardware on a boat benefits from basic corrosion prevention, especially in saltwater. When mounting against stainless fasteners or dissimilar metals, simple isolation steps like suitable bedding and insulating washers help reduce galvanic staining over time.

What’s included
  • Circular baseplate
  • 3 x M6x14 mounting screws
  • Instruction manual
Use cases on board

This baseplate makes sense for owners keeping spare parts aboard, yards doing navigation light replacements, and anyone reworking the mounting area for a horizontal light on a cabin top, hardtop, or arch where you want the light to sit flat and stay properly secured.

Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer. For certain international orders, inventory transfers between warehouses may add time. If any delay is expected, we will let you know the dispatch date.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

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.

We are happy to help you find the right contact or documentation, but we cannot decide outcomes or intervene in claim resolutions. For guidance, email cs@qualityboatparts.com.
