Replacement boat bulbs are essential for ensuring safety and compliance with maritime regulations. They can be used for navigation, anchor, cabin, headlights, instrument, and courtesy lights. It's important to choose bulbs that are resistant to humidity and vibration and compatible with the marine electrical system (12V or 24V).

💡 Main types of nautical light bulbs

1. LED (12/24V) Navigation, courtesy, dashboard, headlights -> Long life, low consumption, wide range
2. Halogen (12V) Headlights, projectors, interior lights -> Warm light, high consumption, less resistant
3. Incandescent (old systems) Navigation or instruments -> Obsolete, replaceable with compatible LEDs
4. Xenon or HID Driving lights or searchlights -> High intensity, require ballast
5. Bayonet (BA15s, BAY15d) Navigation lights -> Check base and polarity
6. G4 / MR11 / MR16 Interior lights, spotlights -> Often replaced by LED equivalents
7. Festoon (SV8.5) Anchor or internal lights -> Tubular format, various lengths
8. T10 / W5W Instrumentation, indicators -> Commonly used in cars too
