Morimoto 2Stroke 4.0 LED headlights, H11/H9/H8, for 2004-15

Meet the new Morimoto 2Stroke 4.0 LED, the successor to the very popular 2Stroke 3.0. No LED bulb in the world more closely simulates the filament size of an incandescent bulb. With a 1.45mm surface emission interval (a fancy way of saying the distance between the chips) it is the closest LED on the market to matching the filament width of an incandescent. By imitating the stock halogen bulb, the 2Stroke 4.0 can recreate the original beam pattern, which casts a greater amount of light on the road and reduces glare for oncoming drivers.

The benefits don’t stop there. The 4.0 uses a new and unique drive rate logic to maintain consistent intensity over time by ramping up power over the first 15 minutes of use. This feature eliminates the loss of intensity found on other LEDs as they heat up. A unique locking adjuster mechanism allows for infinite adjustment to ensure the LED chips point exactly to 3 & 9 o’clock and ensures the adjustment will not slip during installation. Their patented 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. This effectively cools the bulb while warming the ambient temperature inside the housing, increasing resistance to snow/ice buildup on the lens during the winter months. They are also significantly quieter than other fan-cooled LEDs. They are offered with a limited lifetime warranty.

As the name indicates, this LED is designed to fit H11, H9, & H8 applications. The H9 is the correct bulb for the NC high beams as well as many other applications. The H11 is the correct bulb for the 04′-05′ & NC fog lights, as well as many other applications.

Note that if you have your fog lights on at the same time as these high beams, the high beam indicator will illuminate partially instead of fully. This doesn’t hurt anything, although you can restore functionality with these resistors. Bear in mind that they’ll get hot with long-term operation, so be sure to locate them accordingly. This is only an issue when you use these bulbs as high beams, there are no issues when you use these bulbs as fog lights. 

Canadian NCs use the high beams at half power as their DRL. These LEDs are not compatible with this use and will either flicker or fail to light.

HID and LED bulbs are street legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. Legal for off-road use in Snowmobile and ATV headlights and off-road racing use only auxiliary or forward lighting. International street legality varies by country. Note: This usage regulation is not unique to Morimoto bulbs. All LED and HID bulbs from all other brands, regardless of marketing claims, are prohibited from street use in halogen headlights in the USA.
