Thanks to its sleek 1.45mm emission surface and advanced PCB technology, you're guaranteed optimal performance. Enjoy precise beam distribution that ensures every drive is bright and secure. Plus, its adjustable base fits various reflectors, and the built-in cooling system promises longevity, even in extreme conditions. Upgrade now and light up your journey with confidence!

Benchmark

While others in the industry have lagged behind, Morimoto has been busy perfecting the successor to the impressive 2Stroke 3.0 LED bulbs. The 4.0 effectively recreates the original beam pattern from your optics, doing more with less. This means more light on the road for you while reducing glare for oncoming drivers. Though LED bulbs aren't DOT approved for headlights in the U.S., international markets and fog light users can enjoy the best plug-and-play LED bulb available today: the 2Stroke 4.0, featuring patented technology by Morimoto.

Superior Beam Quality

The advanced Aluminum Nitride Ceramic circuit board at the heart of the 2Stroke 4.0 ensures the most precise beam pattern possible, with its 1.45mm surface-emission interval. For comparison, a tungsten filament in a halogen bulb measures 1.4mm, while the previous LED record was 2.0mm with the outgoing 2Stroke 3.0. By utilizing the industry-first ceramic PCB, we've eliminated the need for a dielectric layer and a separate thermal element. Combined with the Osram Oslon HJL531.TE LED chips, this results in unmatched performance in all reflector and projector-based headlights designed for halogen bulbs.

Optimized Focal Length

Each size in the 2Stroke 4.0 lineup has been meticulously optimized for its intended application. The critical reference distance is calculated based on the bulb base's geometry and the footprint of the Osram HJL531 emitter. To ensure consistency, we've designed special tools to quality-control each bulb as it comes off the production line. Unlike most other LED bulbs that use a 'set it and forget it' reference distance, the 2Stroke series offers optimal focus tailored to each application.

360 Degrees of Rotation

With no universal standard across different headlight and fog lights, all bulbs in the 2Stroke 4.0 range are fully adjustable. You can easily position the LED chips to sit perfectly at the 3 and 9-o'clock positions. The previous generation's base gears were prone to slipping, but our new system has resolved that issue. Setting up the alignment of your bulbs has never been easier!

Thermal Management

The 2Stroke 4.0 features an upgraded version of the patented cooling system first introduced with the 3.0 bulbs. This innovative system uses a 12,000-rpm dual-layer fan to draw cool air into the bulb while expelling warm air back into the housing. Cold air is pulled in past the PCB sidewall to exchange heat, while warm air is blown out the opposite side, effectively cooling the bulb. This design increases resistance to snow and ice buildup on the lens during winter months. With enhanced static pressure, the cooling system on the 2Stroke 4.0 maximizes bulb longevity and provides a bad-weather benefit that?s hard to find elsewhere.

Unique Drive Logic

The LED drivers are programmed to start at a gentle 18W and gradually ramp up over the first 15 minutes, stabilizing at 22.5W. Unlike other aftermarket bulbs that lose output intensity during the initial runtime, the 2Stroke 4.0 maintains impressive performance from the moment you hit the road until you park your car.

Lifetime Warranty

Crafted with the latest OE-grade materials, electronics, and LEDs for the automotive industry, the Morimoto 2Stroke 4.0 bulbs are built to last. Their conservative drive rates and effective thermal management contribute to low operating temperatures. This all adds up to a bulb designed for longevity, which is why we proudly back it with an industry-leading lifetime warranty.
