Overview posters

Advanced optical technology

The DRG03 uses an advanced triple direct LED optical system, promoted by NHK with “Sky bat optics” styling, to maximise beam spread while keeping a strong central hotspot. The result is excellent road coverage with a sharp, controlled beam pattern.

• Triple LED projection: delivers wider beam coverage and improved visibility.
• Three independent high beams: designed for stronger long-range performance.
• Hyperboloid spherical lens: engineered for longer range and stronger penetrating power.
• Balanced light distribution: strong foreground coverage with extended distance reach.
• Non-dazzling output: sharp cut-off helps reduce glare to oncoming traffic.

Cooling and durability

The Stormbringer DRG03 is engineered for stable long-term output with an advanced heat dissipation system designed around airflow and active cooling.

• Honeycomb isometric ducted wind tunnel design for unobstructed airflow
• Dual ball-bearing imported smart fan for reliability and long service life
• Stacked surface heat dissipation structure for thermal stability
• Twin-turbo fan blades for powerful cooling performance

Beam performance

The DRG03 is designed to produce a clean and controlled beam for both daily use and performance-focused retrofit builds.

• Low beam: sharp cut-off, glare-free, stable output, and no visible flicker
• High beam: long-range projection with a focused, penetrating beam
• Wide beam spread: improved roadside and forward visibility

Frequently Asked Questions

Technical specifications

Fitment may require vehicle-specific brackets or spacers depending on housing design and retrofit method.

Installation

Uses the G5 bracket-hole pattern (Hella G5 / 3R compatible) for retrofit mounting. The built-in 12 V driver connects directly to existing low and high beam circuits, removing the need for an external ballast.

For correct aim, sealing, and safe operation, professional installation is strongly recommended.
