Adventure Lights Guardian Expedition Light, Red

Best dog collar light on the market! I've used an older model for 20 years and still works great, this one does not have to return bend on the clip and it falls off sometimes. The new one has the return bend, great improvement.

Great light we are seen at night clips on dogs collar easy

Good and bright. Belt clip mounts solidly. The PROBLEM is: to disassemble the light, you twist off the cap. To turn on the light, you twist on the cap. This means that you twist it off to turn it off. So its a delicate balancing act to keep it turned off, and eventually the cap works itself off and shoots into the shrubbery off the trail, never to be found again.I'd like this a lot better if it had a locking mechanism and a more positive switch. As it is, its a poor design.

I use this light clipped to my swim goggles for night time Marathon swims. It's waterproof.REALLY!

personally rated -45F with wind chill, Good strobe and steady burn. battery lasts a long time. Fits well on molle and belts.

These are going to be great for camping beacons or to go on my back when I walk at night.

Great lights. Work well.

--------------------------------Bottom Line--------------------------------Not recommended because it failed after 4 months of neighborhood dog walks in ideal conditions. I would absolutely not count on this light in an emergency, particularly if your life depends on its function. For this, I would look into something more robust such as the Adventure Lights V.I.P. ($150) series or another brand entirely. For dog walks you may want to look into bike lights; they are fairly light, the good ones are waterproof (look for IPX rating), and many have an option to swap out the seatpost attachment for a standard clip that can be mounted to clothing or a dog collar / harness. Additional details:--------------------------------PROS--------------------------------[1] Beam pattern is unique and more functional than most bike lightsThis has a beam pattern that is unique to "beacon" - style safety lights and is almost never found in a bicycle light meant for traffic use. You can see in the product photo that the dome has two components; a diffusion ring at the base and a magnifying lens at the top. Light emitted by the LED is scattered by the diffuser in a panoramic 360 degree fashion while the rmagnifying lens focuses the light into a narrow but BRIGHT beam through the dome. The result is a combination beam pattern that is seen extremely well at distance AND at distance. This is unique! Bike lights are designed to reflect and magnify their output directly towards traffic traveling in-line with the rider. They almost never have more than 10% side-visibility. This is fine for dog visibility on-leash on a sidewalk, but lost, scared, squirrel chasing dogs don't follow traffic patterns; bike lights are unlikely to be pointed towards oncoming traffic in those unpredictable circumstances, especially if the light is mounted to the top of the harness or one side of a collar.[2] WaterproofThere is a rubber gasket with screw-down dome that inspires confidence in this claim. Because the light activates without screwing down the dome entirely, there's a real possibility the user will fail to seat the gasket properly. An improperly seated gasket will result in a light that fails in a sustained downpour or submersion (in a puddle for example) for any length of time.[3] Mounting optionsThis comes with a clip that can be removed and replaced with other mounting attachments. You can mount it to hunting-dog collars with a wider width (SportDog) through the clip or take the clip off and mount the light directly to more narrow webbing through the slots on the light itself. You can see the attachments on the Adventure Lights website or DIY with velcro, armbands, headbands, Molle, etc.--------------------------------CONS--------------------------------[1] Failed prematurely.The most extreme circumstance the light encountered was my dog shaking back and forth while it was attached to his harness and 3 x 20 minute walks in drizzle. After 3 months the twist-activation mechanism would no longer reliably activate and a month later the light failed entirely. Changed the coin cells out to new energizers and inspected circuit under magnification; no clear cause identified.[2] Expensive compared to competitionThe most popular mainstream product (for dogs) is the Nite-Ize Spot-Lit ($5) or its generic counterpart ($1-2), both of which I own. Those lights will also fail but at least they are expected to (amazon even includes the disco color in their subscribe and save program). For the price of this light I could have gotten 12-15 of those. I expect them to last 4 months each which puts me at 4-5 years of use for the same price as this product.[3] Weighs collar down so it always points to groundThe light is heavy enough that it causes the collar to rotate and the light always ends up pointing straight at the pavement and the visibility to oncoming traffic will be severely limited. This is solved by clipping 2 units directly opposite one another (expensive) or clipping it to the top of a harness. I think mounting one light on each side of the dog is exponentially safer than a single light on top but maybe I'm just a safety nerd.
