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. H11 Tension Spring: The base of the of the 2Stroke 4.0 H11/H9 bulbs has an integrated tension spring that pushes the entire bulb base downward with 5nm of force, resulting in a bulb that's been properly seated according to the needs of optics. The complexity and cost that went into developing these parts alone was a significant investment, but one we had to make in our continuous pursuit of perfection. We would be impressed if you could find another brand who cares enough to make this kind of investment on this often-overlooked feature. 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:

Great for teething puppies
Color: Dogwood (Brown), Size: Small (Pack of 1)
My pup absolutely loves this. Can keep him occupied for up to 45 min at a time. Pretty durable, too.

The best chew ever for a strong chewer
Color: Dogwood (Brown), Size: Large (Pack of 1)
We have a 77lb goldendoodle who loves these. We’re lucky because he doesn’t chew on anything other than his toys, but when he starts on this…he really goes at it. It’s healthy, (not synthetic), doesn’t break apart, (no pieces to worry about him swallowing), it just perfect for him. The noise may get on your nerves but it’s a small price to pay to keep him from chewing on your furniture, shoes, or anything else a mischievous dog can find.

Little pieces break off
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is obsessed with this. It does last a long time even given her strong chewing capabilities. I wish it was a little bigger. The main reason I rated it so low is when my dog is chewing on this it breaks off a little plastic peice and sometimes it hits the back of her throat making her cough so you have to supervise with this.

Great for aggressive chewers
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is an aggressive chewer so they are great for her. I would love to have one a bit thinner so it could fit in a holder so it is easier for her to hold while eating. This keeps her busy and is long lasting. I have purchased these multiple times.

Not the most durable, but my dog LOVES it.
Style: Plush Surprise Color, Size: 24"
My boyfriend’s dog had the small version from Petsmart and she has been very gentle with it since she likes it so much. I decided to surprise her with this 24 inch one for Christmas. She was obsessed! It’s cute, it’s very soft, and has a big squeaker in the top, which she loves! She was a little more tough on it and it did get some rips 12 hours in, but it is still in one piece at the moment and brings lots of joy. The dog is a medium/large size.
Dog toys can be so expensive. I personally think the was a great price despite not being the most durable. I may purchase again next year!
