Ziomitus T10 LED Wedge Bulbs 10-Pack — 6000K Cool White, 2W Low Power, Ceramic Heat-Sink for 12V/24V RV & Marine Interiors

Ziomitus 10-pack T10 LED bulbs replace 921/912/194/168 wedge bulbs with bright 6000K light, low 2W power draw, and ceramic heat-sink durability for 12V/24V RV and marine interiors.

These compact wedge LEDs are engineered for camper, trailer, motorhome and boat interior dome lights and a wide range of exterior marker and license applications. Each bulb delivers roughly 350 lumens from only 2W, uses a ceramic heat-sink and polycarbonate cover for improved thermal performance and impact resistance, and is rated for about 30,000 hours. They accept AC10–24V or DC10–30V, fit many OE wedge sockets, and come in a 10-pack for multiple fixtures or spares.

Will these LEDs fit my existing T10/194/168 sockets?

The Ziomitus bulbs are designed to match a broad list of T10-style wedge sockets used in many vehicles and boats. They explicitly list compatibility with common OEM numbers like 921, 912, 194, 168 and several PC/ W5W variants, but physical fit can vary by trim.

• Voltage range AC10–24V and DC10–30V supports 12V and 24V systems.
• Compact dimensions: approximately 0.53 x 1.12 inch to suit tight dome housings.
• Check your owner’s manual or original bulb number to confirm fit before ordering.
• If the LED doesn’t light, reverse polarity by flipping the bulb 180 degrees.

How bright and efficient are these 6000K LEDs for interior use?

Each bulb emits about 350 lumens at a cool 6000K color temperature, producing clear bright white light useful for reading maps or lighting cabin spaces. At roughly 2W per bulb, they consume far less energy than halogen equivalents while producing around three times the perceived brightness.

• 350 lm output per bulb for strong interior illumination.
• 2W power draw helps preserve RV/boat battery life.
• Cool white 6000K for crisp, daylight-like visibility.

What makes the Ziomitus design different from typical T10 bulbs?

Instead of standard plastic housings, these LEDs use a ceramic heat sink to dissipate heat more effectively and extend component life. A polycarbonate (PC) lampshade adds impact resistance and flame-retardant protection, improving durability in mobile environments.

• Ceramic heat sink for improved thermal management and longer lifespan.
• PC cover for waterproofing, impact resistance, and safety.
• Quality LED chips and driver chosen to reach ~30,000 hours life expectancy.

Are there installation cautions or compatibility limits I should know about?

These LEDs are non-dimmable and may not behave correctly with halogen transformers or specialized dimming circuits used under counters or in retrofits. They are polarity-sensitive—flip the bulb if it doesn’t light—and small size differences across trims mean measuring is recommended.

• Non-dimmable: may flicker with halogen transformers; use an LED-specific driver where needed.
• Polarity sensitive: rotate 180° if the bulb fails to illuminate initially.
• Confirm bulb model/size for exact fixture fit to avoid clearance issues.

Who is this for: Ziomitus 10-pack T10 LEDs suit RV and boat owners, overlanders, and anyone replacing multiple interior or marker wedge bulbs who wants brighter, cooler light with lower energy use and durable construction. They are a practical upgrade for dome lights, map lights, license and marker lamps when you need compact, long-lasting white illumination and ruggedized materials for mobile environments.
