Grandview 12V COB LED Car Interior Dome Lights 10-Pack — 8000K Bright White, 48-SMD, Includes Adapters

These Grandview 12V COB LED dome lights are a 10-pack of ultra-bright, energy-efficient interior bulbs that include adapters for festoon, T10 and BA9S sockets.

Upgrade cabin lighting with a kit designed for easy swap-outs and wide compatibility. Each panel uses a COB array with 48 SMD chips to deliver roughly 480 lumens at 12V while drawing only 0.12A, offering bright white 8000K illumination that lasts up to 50,000 hours. The set ships with three adapter styles so you can fit common dome, map, dashboard and license plate sockets without soldering.

How bright are these COB LED dome lights compared to stock bulbs?

These COB panels concentrate 48 SMD LEDs into a compact 40 x 35 mm module, producing about 480 lumens per unit. That output typically equals or exceeds OEM incandescent bulbs while using far less current, so you get noticeable brightness without added electrical load.

• 480 lumens per bulb for clearer cabin illumination
• 48 SMD chips on a single COB surface for even light distribution
• Rated 8000K for crisp white light that improves visibility
• Low draw: ~0.12A at 12V for energy efficiency

Will these fit my vehicle’s dome, map or license plate lights?

The kit includes 10 adapters to match the most common socket types: festoon (31–42mm), T10 (9mm) and BA9S (9mm). Because vehicle sockets and panel spaces vary, confirm the bulb housing dimensions and socket style before installing. If a bulb doesn't light, the panel is polarity-sensitive—simply flip the adapter.

• Includes festoon, T10 and BA9S adapters for wide compatibility
• Measure original bulb length (31–42mm festoon range applies)
• Polarity sensitive—reverse adapter if no illumination
• Designed for 9–16V systems; match to 12V vehicle wiring

How easy is installation and what precautions should I take?

Installation is plug-and-play: match the included adapter to your socket, push the connector into place, and verify the orientation. The panels come with self-adhesive backing for mounting where a clip or flat surface is preferred. Always disconnect power when swapping bulbs and check fit to avoid stressing the housing.

• Plug-and-play wiring with pre-attached adapter leads
• Self-adhesive tape included for secure mounting options
• Disconnect battery or power before replacing bulbs
• If not lighting, remove and reverse adapter to correct polarity

How durable are these LEDs and what environments are they suitable for?

Grandview COB panels are built for long service life—up to 50,000 hours—while consuming minimal power. They resist frequent on/off cycles and are suitable for interior uses such as dome, reading, dashboard and license plate lights across cars, trucks, RVs and campers. Avoid direct exposure to open water; they are intended for vehicle interior and protected exterior fixtures.

• Estimated lifespan: 50,000 hours under normal use
• Low power consumption reduces heat and stress on socket wiring
• Fast on/off response with no warm-up time
• Intended for interior and protected exterior lighting applications

Who is this for: This 10-pack is ideal for DIYers, fleet owners, and vehicle hobbyists who want a reliable, affordable interior lighting upgrade across multiple vehicles. It’s also useful for owners of older cars, RVs and trailers who need to replace several bulbs at once and prefer a kit that includes the common adapters and mounting options.
