H4: Morimoto 2Stroke 3.0


PART #: 2 x LED1525

[ In Stock: 0 pieces ]


Product Details

Benchmark: Over the course of the last year, Morimoto was hard at work developing a new kind of LED bulb. It 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 3.0.

Integrated Micro-optic Reflector: The 2Stroke 3.0 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% of the raw lumens are projected on the road as forward illumination. With this special optic, about 40% 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 patent-pending feature a serious performance advantage over other H4 LED headlight bulbs. US Patent #11079090 (Click for Details)

Superior Beam Quality: The advanced PCB technology at the core of the 2Stroke 3.0 sets a new industry benchmark emission surface interval of just 2.4mm total. The PCB core itself is just 1.0mm thick. The dielectric layer: 300um. The circuit pattern: 140um, and the Philips Lumileds Luxeon Z LED chips: just .59mm each. Paired with the tight light-emitting surface area of the LEDs: this adds up to a total cubic volume of 4.46mm. At the end of the day, no LED bulb in the world more closely simulates the filament size of an incandescent bulb more accurately than the Morimoto 2Stroke 3.0--and for those in the know, this is critical when it comes to proper beam distribution.

Optimized focal length: Each size in the 2Stroke 3.0 lineup has been painstakingly optimized for proper output in its designated application. The critical reference distance has been calculated based on the geometry of the bulb base and the footprint of the Osram HKL emitter. To ensure consistency, special tools were designed to quality-control the accuracy of each bulb as it comes off the production line. Most other LED light bulbs on the market use a 'set it and forget it' reference distance across all sizes in the series, which is not the case here.

360 degrees of Rotation: The 2Stroke 3.0 LED bulbs feature a fully adjustable base. In order to fully utilize the optical facets in any reflector or projector: The light emitting diodes must face the 3-o-clock and 9-o-clock positions. Since no single standard exists across different headlight and fog light assemblies, all bulbs in the 2Stroke 3.0 range are fully adjustable. A geared step rotational adjuster mechanism is installed for all bulbs which twist-to-lock, offering adjustability in 15-degree intervals. An omni-adjustable rotation mechanism is utilized on all bulbs that are press-fit or clip into the housing.

Thermal management: Once the bulb is installed, the high-speed fan contained within is completely sealed, making the 2Stroke 3.0 the first actively cooled LED bulb with a fan that's not susceptible to outside elements. Their unique internal circulation cooling system uses a 12,000-rpm cyclone fan to suck cool air into the body of the bulb and blow warm air out, back into the housing. On the intake side, cold air is sucked in past the sidewall of the PCB to exchange heat and is blown out the opposite side of the bulb. This effectively cools the bulb while warming the ambient temperature inside of the housing, increasing resistance to snow/ice buildup on the lens during the winter months. The cooling system on the 2Stroke 3.0 not only does it's job to protect the longevity of the bulb, but serves up a bad-weather benefit not found elsewhere. (Patent Pending)

Advanced Driver: The LED Driver on the 2Stroke 3.0 H4 Bulbs is made of die-cast AL that's been electroplated. It has a double-lip seal, and has been completely potted. In combination with the high-quality over-molded wiring, these bulbs are all-weather ready.

Installed these on a 2010 Yaris. They are bright. The beam pattern is matched perfectly. Liked how the bulb can rotate though that was not needed in my situation.

Only part and I should knock a star is the dust cap. The Yaris has the hole in the back that the bulb connection pokes out of so obviously the heat sink and cable were an issue. Just had to take a knife and do some cutting so the heat sink fits through.

They really work, install was a little tricky.


Initially I wasn't sure how much difference there was but after driven with the lights for a few days they are much better. You can look at measurements all day long but I can tell you they are functionally better. Install was a little tricky in my application. Some trimming of the rubber boots was needed. The h4 clip also fit a little tighter than normal as the metal base is much thicker than the original stamped metal style bulb base. I have yet to use this style of led headlight bulb before so I have no comment on comparison for that. But this is highly recommended vs stock incandescent.

Bright Light in the Right Places!

Spencer Landers

I've owned other LED bulbs in the past, and they've always been hit or miss. Having plenty of excellent past experiences with Morimoto HID setups, I knew their LEDs wouldn't disappoint. And they do not! I installed a single H4 2Stroke in my 2018 Suzuki DRZ400SM supermoto. It has a simple, old-school, square glass headlight housing that really limits the possibility of retrofits or full replacement housings. The Morimoto unit dropped right in, with minimal bulk behind the headlight housing which works perfectly in the low amount of space available on most bikes. The light pattern on low beam and high beam is identical to that of the original bulb, but about twice as bright. No goofy glare, no distortion of patterns. I contacted TRS about availability of a single bulb so that I did not have to buy a pair, and a single unit was placed in my cart the next morning!

Just what I needed!

Jonathan Patterson

Had old headlights in my 2010 Tacoma and needed the upgrade. Wanted to go with a trusted product and have been super satisfied with these. Very easy install on the Tacoma as well. Did not modify a thing the rear simply presses tight against the rubber housing. Would for sure recommend.

Love these lights...but...

Pat Conlin

I love my new 2 Stroke 2.0's. I live in a rural area and work swing shift so I'm going home late in the evening. These lights are EXTREMELY bright and REALLY light up the road...they really do the trick!!

The only downside is for the on-coming traffic! I get about 25% of the on-coming traffic flashing me thinking my brights are on! They really hate it when I flash them back....

Overall these lights do exactly what I wanted them to do...light stuff up! The beams are well focused and not the usual flood-like affect like other LED's or HID's without projectors....love them!!

Let there be light!

Jonathan Patterson

Put these on my 10 Tacoma and I'm thrilled! The fit with no modification even to the housing boot. They are a full leap beyond the stock bulbs and I would recommend them to anyone.

Pretty Decent

Michael Bong

Installed these in a 2005 Tacoma. The cutoff looks pretty solid against a fence, though I think they'll need to be re-aimed. I had someone else drive the truck head-on towards me and the lights hit the eye just a little wrong. Just haven't gotten around to aiming them down a little to see if that takes care of it.

Factory rubber boots were able to be re-used, though they fit really tight on the base of the bulb. Wasn't able to get the fan holes outside of the boot though, so hopefully that doesn't cause issues with cooling. Fans can be heard in the cab, but once the engine and music are playing you can't hear them.

Hopefully they last, haven't had them in long enough to tell longevity-wise
