Benchmark: While the rest of the industry has been asleep at the wheel in this category; Morimoto was hard at work developing the successor to the incredible 2Stroke 3.0 LED bulbs. The 4.0 re-creates the original beam pattern from your optics effectively by doing more with less. They will put more light on the road for you as the driver, while creating less glare for oncoming traffic compared to any other LED bulb on the market today.

While LED bulbs still aren't DOT approved for use in headlights in the states-- foreign markets and fog light users can enjoy the best plug n play LED bulb to date. The 2Stroke 4.0. (Featuring technology patented by Morimoto) Superior Beam Quality: The advanced Aluminum Nitride Ceramic circuit board in the center of the 2S4 sets allows the bulbs to produce the most precise beam pattern possible, with its 1.45mm surface-emission interval. For reference, the tungsten filament in a halogen bulb is 1.4mm, and the previous record for an LED bulb was 2.0mm, set by the outgoing 2Stroke 3.0 bulb!

Using the industry-first ceramic PCB, we have eliminated the need for the dielectric layer and a separate thermal element, which, in combination with the Osram Oslon HJL531.TE LED chips makes for unmatched performance when used in all reflector and projector-based headlights designed for halogen bulbs. Integrated Micro-optic Reflector: The 2Stroke 4.0 H4 bulb has an innovative low beam shade cup with a built-in micro-optical reflector inside that enables their ability to illuminate reflector surfaces above the bulb. In a typical H4 application, only about 30 percent of the raw lumens are projected on the road as forward illumination.

With this special optic, about 40 percent of the lumens will be projected onto the road. The region of the reflector directly above the bulb is responsible for a critical amount of light within the beam pattern, making this patented feature a serious performance advantage over other H4 LED headlight bulbs.
