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% 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 patented feature a serious performance advantage over other H4 LED headlight bulbs. US Patent #11079090 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's why they are backed with an industry-leading lifetime warranty.What's Included:

My dog loves it
Size: 25in, Style: Sport
I am amazed at how far I can throw a tennis ball. My dog and I absolutely love this. What happens to work well with the squeaky balls?I get on amazon as well. I have one of these at home, And I keep another one in the truck.
Very durable, The balls have good bounce, My dog and I have a lot of fun with it. My dog doesn't chew much on balls, But this one seems like it's going to stand out, I love the versatility, Hey can handle almost ending ball that same size. Are you solid rubber bouncy balls, Squeak.
Ing tuba balls, Whiffle balls with all the holes in it, Even the squeaky chewing balls. As long as there are that same size.
love the product. I've been using them for a few years.

Durable
Honestly I didn't think this ball would last but 2 years later and only one battery change later and it is going strong. This ball has given me so much more time to play with my dog since I can throw the ball at night on short winter days I can't recommend it enough. I can throw the ball at night and my dog can find it in the dark. Add a collar LED and it's a funny light show of one light intercepting another.

Great for pm at the park!
This is alot like Nite Eyez but not as good but if you have never used Nite Eyez you will love this!! I have an am. staff that i take to the park at night so she can run around without the fear of a dog running up on her (she doesn't like that) and this ball is great! Stays lit and changes colors and it she cant destroy it!

Works Great!
This is a new version of an old style that was the best most durable, and long lasting night time balls!!! They stay on long enough for me to find if my lab cant find it. (We have an acre backyard and in ground swimming pool) sometimes I have to retrieve it. Stays on and auto shuts off after inactivity. They ARE waterproof and we play in the pool with them on night swims. My lab is very hard on balls, very few hold hold up to his chomping on them. Great balls!!

not worth the cost
I love these balls for night time ball playing but they dont last. The last 4 Ive bought havent worked well or lasted more than a month. They were once worth the money
