Hella Marine DE3175 Festoon Replacement Bulb, SV8.5-8 Base, 12V, 10W

Overview

The Hella Marine 002091361 is a 12V, 10W clear festoon replacement bulb with an SV8.5-8 base for fixtures that use this style of end-cap bulb.

It is commonly used in navigation lights and interior lamps that take an SV8.5-8 festoon, keeping the original light color and beam pattern that the fixture was built around.

For best results, confirm your onboard supply is 12V DC and that the light is rated for a 10W bulb (about 0.8A draw at 12V).

Key features

• 12V, 10W festoon bulb with SV8.5-8 end caps
• Clear glass for the same light color your lens and filter expect
• Drop-in fit for fixtures that use an SV8.5-8 festoon holder, including many navigation and interior lights
• About 0.8A current draw at 12V, useful when checking fuse and circuit loading
• Simple replacement that does not change wiring, switches, or housings

Compatibility and fit

Match the base style first: SV8.5-8 festoons use spring contacts on each end, not wedge or bayonet sockets. If your old bulb has the base code printed on the metal cap or the fixture calls for SV8.5-8, this is the correct fit.

Because festoon lengths vary, compare the old bulb end-to-end before ordering if your fixture has tight tolerances.

Installation and setup

Turn off power at the switch and, if possible, the breaker. Let the lens and bulb cool before handling. Remove the lens, then compress one end of the bulb into the spring contact and seat the opposite end.

Clean any green corrosion from the contacts so the bulb seats firmly; poor contact is a common cause of flicker on boats.

Use cases on board

This bulb suits 12V boats that still run traditional festoon lamps in navigation lights, cabin domes, chart lights, and courtesy fixtures where the housing is built around an SV8.5-8 bulb and a 10W load.

It is a good match when you want a like-for-like replacement without changing fixtures or dealing with LED polarity and dimmer compatibility.

Maintenance and care

Keep the lens gasket and venting in good shape so moisture does not sit in the fixture. If you routinely wash down with saltwater, a quick rinse of the lens area and an occasional contact check will help prevent future failures.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
