Automotive Halogen Bulb Pair

The GP Thunder SGP58K-H3 is a pair of H3 halogen bulbs built for drivers who want a brighter, whiter beam from standard 12 volt headlamp, fog or daytime running light housings. They suit owners seeking a simple plug-in upgrade without rewiring or ballasts.

5800 Kelvin 55 Watt Output

Each bulb runs at 55 watts and produces a 5800 K plasma white colour that sits between the warmer 3500 K option and the cooler 7500 K and 8500 K variants. The quartz glass envelope handles the heat of continuous high-beam use, though the fixed 55 watt rating means they cannot match the raw lumen output of higher-wattage or HID systems.

Quartz Glass Construction

Fused quartz glass allows the compact bulb to sustain maximum power in a smaller footprint than standard glass. No switch, wiring harness or driver module is included, so installation relies entirely on the vehicle’s existing H3 socket and factory wiring.

Questions about this item

Will the H3 base fit the halogen socket already in my car?

The bulbs use an H3 base designed for standard 12‑volt halogen sockets, so they drop into the existing housing without adapters.

How can I confirm the 5800K colour temperature once they are installed?

Switch on the high beams; the output should appear as a crisp plasma‑white rather than yellow or blue‑tinged light.

Are both bulbs included or do I need to order a second pair?

The pack contains two H3 55‑watt quartz‑glass bulbs — one pair — so nothing else is required for a full high‑beam swap.
