Morimoto H4/9003 2Stroke 4.0 LED Bulbs (Pair) – 5500K, 2600lm, Lifetime Warranty

Upgrade your lighting the right way with the Morimoto 2Stroke 4.0 H4/9003 LED Bulbs — engineered to replicate halogen-style optics while improving usable light on the road. With a focus on beam control (not just marketing lumens), the 2Stroke 4.0 delivers a cleaner cutoff, improved forward visibility, and reduced glare compared to typical LED conversions.

Built around an ultra-precise emission surface and a 360°-adjustable base, these bulbs are designed to dial in the correct LED chip orientation for your reflector or projector housing. They also feature a high-performance thermal management system and are backed by a lifetime limited warranty when purchased through authorised channels.

Key Features

• High beam control: engineered to recreate the original optics pattern and reduce glare
• 360° rotation: adjustable base for correct LED chip alignment in varied housings
• Smart drive logic: power ramps from 18W to 22.5W for sustained output
• OE-grade materials: built for reliability and long service life
• Lifetime limited warranty: manufacturer-backed support (authorised purchase required)

Compliance & Road Use

These bulbs are not ECE homologated and are supplied for off-road applications. They are not offered as approved LEDr replacements for road-use halogen headlamps. Great Britain's MOT change from 14 October 2026 concerns approved LEDr products in compatible halogen units with the required secure approval sticker; it does not establish approval for this product. Do not assume a retrofit is road legal because the bulb fits. Other lighting and vehicle-use requirements remain applicable.
