533% Brighter than Stock Low Beam Bulbs! In 2013 the Ram 1500 sport trucks came out with a new headlight that used a dual beam projector for the low beam but also a normal style reflector high beam. Although the headlights look better than the older style, performance is still subpar at best. We tested a dozen different popular LED headlight bulbs and found that the 2Stroke 4.0 LED bulbs from Morimoto created the brightest light output while retaining a good beam pattern from inside the projector on low beam. In fact these bulbs are so bright that in this application they tested to be 533% brighter than the stock halogen headlight bulbs!

It's important to select your correct model year because based on the year they came with different low beam headlight bulbs. 13 - 15 used a different bulb style than 16 - 18. Also, in 2015 Dodge changed something with how the BCM functions and a special relay harness with built-in resistors is required. If you have a 2015 Ram 1500 the install is more challenging, but it's the only way to make it work, you'll want to follow these instructions (click here) to understand how to use the MOPAR harness from Morimoto.

This kit includes a pair of Morimoto 2Stroke 4.0 LED low beam bulbs, a pair of extended dust covers to help make everything fit, and the PWM module for low beam. Everything demonstrated in the video is included in your kit and if you have any questions on install, we're here to help!

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.

Optimized focal length: Each size in the 2Stroke 4.0 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 HJL531 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, making for sub-optimal focus in most applications... not the case with the 2Stroke series of bulbs.

360 degrees of Rotation: Since no single standard exists across different headlight and fog lights, all bulbs in the 2Stroke 4.0 range are fully adjustable so that you can dial-in the position of the LED chips so that they sit perfectly at the 3 and 9-o-clock positions. On the previous gen bulbs, the gears on the base were prone to slipping when locking it into your headlight, but the new system is immune to that. In summary, setting up the alignment of your bulbs is now easier than ever!

Thermal management: The 2Stroke 4.0 uses an upgraded version of the patented system we first employed on the 3.0 bulbs. This unique cooling system uses a 12,000-rpm dual-layer 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. With even more static pressure than the previous version, the cooling system on the 2Stroke 4.0 maximizes longevity of the bulb, while serving up a bad-weather benefit not found elsewhere.

Unique Drive Logic: The LED drivers are programmed to start up at a conservative 18W, and then ramp-up in power over the first 15 minutes before stabilizing at 22.5W. Unlike every other bulb in the aftermarket which lose output intensity over the first 15 minutes of runtime (as the system heat-soaks), the performance from the 2Stroke 4.0 remains impressive from the moment you pull out of the driveway till the moment you park the car.

Lifetime Warranty: The Morimoto 2Stroke 4.0 bulbs are produced using the latest OE-grade materials, electronics, and LEDs for the automotive industry. The conservative LED drive rates and highly effective thermal management systems make for low operating temperatures. All of this adds up to a bulb that is designed to last, and that' why they are backed with an industry-leading lifetime warranty.

Great low beams!!!


These are the bulbs I've been waiting for. I'm very pleased, easy to install and so much better than the OEM bulbs.
