Dependable #1034 Replacement Bulbs for Marine Bayonet Fixtures
The Sea-Dog #1034 is a general-purpose 12.8V incandescent bulb with a bayonet base, sold as a pack of 2. Built for the demands of the marine environment, these bulbs feature nickel-plated brass bases for corrosion resistance and reliable electrical contact — a meaningful upgrade over standard automotive bulbs that corrode quickly in saltwater air.
The heavy-duty glass housing and reinforced filament are designed to handle the vibration and shock common aboard a moving vessel, giving you longer service life than standard household or automotive equivalents.
Key Features
- #1034 bulb type — bayonet base, direct replacement for fixtures using this standard
- 12.8V DC — compatible with standard 12V marine electrical systems
- Nickel-plated brass base — corrosion-resistant for saltwater environments, positive electrical contact
- Heavy-duty glass housing and filament — break-resistant, vibration-tolerant
- Pack of 2 — a matched pair for immediate replacement or as a spare
Best Use Cases
A reliable stock replacement for navigation lights, anchor lights, cabin fixtures, and courtesy lights that use the #1034 bayonet base on 12V systems. Keeping a pack aboard as a spare is standard practice for any offshore or extended coastal passage.
Parts Desk Insights
Best suited for fixtures that specifically call for the #1034 bulb type — confirm your fixture's bulb number before ordering, as bayonet base bulbs vary in wattage and voltage and are not universally interchangeable. If you're looking to reduce power draw and extend bulb life, the Scandvik LED bayonet replacement range is a direct upgrade path: see the Scandvik 41104P, 41101P, or 41102P LED replacement bulbs (10–30V, G4/Bayonet/Festoon compatible).
