Marine & Boat LED Bulbs: Navigation, Indicator & Beacon Light Replacements
Marine and industrial lighting has to survive what automotive and household bulbs never face: salt spray, constant humidity, heavy vibration, and wide, non-standard supply voltages. MIDCARS manufactures the full marine light-source family in-house — navigation lights, indicator lights, forklift beacons, and tubular cabin bulbs — across the bayonet (BA15d / BAY15d / BA15s), screw (P28S), and S25 bases, with IP66 / IP68 protection and a comprehensive discrete voltage range covering 10–36V DC, 48–80V DC, and 100–240V AC.
Choosing by Voltage: The First Decision
Voltage is the single most important factor in marine and industrial replacement, because vessels and equipment run on many different supplies. We build each light source for a specific discrete voltage band — never one bulb stretched across incompatible voltages.
| Voltage range | Typical application | MIDCARS coverage |
|---|---|---|
| 10–36V DC | 12V / 24V small craft, yachts, forklifts, vehicle-based systems | Yes |
| 48–80V DC | 48V marine systems, forklifts, industrial control equipment | Yes |
| 100–240V AC | Large-vessel shore power, cabin lighting, marine appliances | Yes |
Base Types We Cover
- BA15d / BAY15d — dual-contact bayonet, used for navigation and indicator lights and forklift beacons.
- BA15s — single-contact bayonet for single-function indicator and beacon circuits.
- P28S — single-contact screw base for high-output navigation bulbs (IP66 / IP68 rated).
- S25 — double-contact bayonet used in navigation light fixtures.
- B22 / E14 / E27 — screw/bayonet household-type bases for 100–240V tubular cabin and appliance lighting.
How to Choose the Right Marine / Industrial LED Bulb
- Confirm the supply voltage. Measure or read the plate voltage first: 12V/24V, 48V, or 100–240V AC. This determines the whole product family.
- Match the base. Identify the old bulb's base — BA15d / BAY15d / BA15s bayonet, P28S screw, or S25 — before ordering.
- Check the protection rating. For exposed decks, mast lights, and wet areas, choose IP66 or IP68; for dry interior fixtures, a lower rating is acceptable.
- Match the equivalent wattage. We offer 25W, 40W, and 60W-equivalent outputs to replace legacy incandescent and halogen bulbs one-for-one.
- Confirm the light color. Navigation lights are color-regulated — red for port, green for starboard, white for stern and masthead — so confirm the required color before ordering.
- Order a sample batch. Test fit, color, and brightness on your actual fixtures before committing to volume.
Common Applications
- Marine navigation lights (port red, starboard green, stern/masthead white)
- Marine and train indicator lights
- Forklift and industrial vehicle beacons (BA15d / BAY15d / BA15s)
- Marine cabin and appliance tubular lighting (B22 / E14 / E27, 100–240V)
- 24V and 48V commercial vessel lighting

LED vs Incandescent: Why Upgrade Marine Lights?
LED marine bulbs last far longer than incandescent and halogen equivalents, draw a fraction of the power — reducing load on vessel batteries and generators — and resist the shock and vibration that quickly destroy filaments at sea. With IP66 / IP68-rated construction, they also withstand the salt spray and moisture that corrode conventional bulbs, cutting replacement downtime for fleet and vessel operators.
Why do marine bulbs need IP66 / IP68 ratings?
Salt spray, deck wash-down, rain, and constant humidity corrode ordinary bulbs quickly. IP66 protects against powerful water jets and total dust ingress, while IP68 withstands continuous immersion — essential for exposed deck, mast, and bilge locations. Choose the rating to match your mounting position.
Should I choose 12V, 24V, or 48V for my vessel?
Match the bulb to your vessel's actual supply voltage — most small craft run 12V or 24V DC, while larger commercial and offshore systems often use 48V or higher. Ordering the correct discrete voltage band prevents flicker, over-voltage failure, and shortened lifespan.
Which base do I need: BA15d, P28S, or S25?
Read the marking on the old bulb or measure the socket. BA15d / BAY15d is a dual-contact bayonet, P28S is a single-contact screw base for high-output navigation bulbs, and S25 is a double-contact bayonet. If in doubt, send us a photo of your existing bulb and fixture.
What is your minimum order quantity?
Standard stock starts from 5 pairs for testing and sampling. For custom packaging, the packaging run has a 5,000-piece MOQ, which is pre-funded and drawn down across your repeat orders. Contact sales02@zhishanled.com for a quotation.
