The H7 bulb is a single-beam headlight bulb standard like H1 and H3, but is defined by its PX26d metal base, two-prong electrical interface, and plastic alignment collar that ensures correct seating in the headlamp. Unlike dual-beam bulbs, the H7 platform supports one beam function per bulb, most commonly used as a low beam, and in some vehicles as a high beam when paired with a separate bulb.
H7 bulbs operate on 12V passenger-vehicle electrical systems with a 55W OEM wattage limit, drawing approximately 4.6A. They are widely used in European-spec vehicles and are especially common in projector headlights, where precise bulb positioning and optics produce a controlled cutoff and reduced glare. Because the bulb itself does not shape the beam, all cutoff and beam distribution depend on housing optics and correct installation using the metal retainer clip or adapter ring.
This Underground Lighting collection contains H7 lighting solutions, covering HID replacement, HID conversion, and high-output LED retrofit use cases. All options exceed the ~1350–1550 lumen output of halogen H7 bulbs and are compatible with modern vehicles when paired with proper CANbus & Anti-Flicker Modules.
H7 HID Replacement Bulbs – 3700 Lumens (PAIR)
These are xenon HID arc replacement bulbs intended for vehicles already equipped with H7 HID conversion systems. Light is generated through an electric arc inside a xenon-gas quartz capsule, delivering approximately 3700 lumens per pair at 35W when paired with a compatible ballast.
Available color temperatures include 3000K yellow, 6000K white, 8000K white with blue tint, and 10000K blue, supporting both weather-focused visibility and appearance-driven upgrades.
H7 HID 35W CANbus Error & Flicker-Free Kit (PAIR)
A complete halogen-to-HID conversion kit engineered specifically for the PX26d H7 format. The kit includes H7 xenon bulbs, 35W electronic ballasts, igniters, and integrated CANbus circuitry.
During ignition, the voltage peaks at ~23,000V to strike the arc, then stabilizes at ~85V AC for sustained operation. CANbus load management prevents dashboard bulb-out warnings, flickering, and ECU faults, especially in 2007+ vehicles.
H7 60W 12000LM CANbus LED Headlight Kit (PAIR)
A high-output H7 LED headlight kit delivering up to 12,000 lumens per pair at 60W system power, producing 6000K daylight-white output. Light is generated via solid-state electroluminescence at a semiconductor p-n junction, providing instant full brightness with no warm-up.
The kit integrates CANbus compatibility to prevent electrical errors and is optimised for projector housings, where correct emitter positioning preserves cutoff sharpness.
