SlimK LED Road Flares Safety Flashing Warning Light Roadside Flare Emergency Discs Beacon, Magnetic Base for Car Motorcycle Bicycle, 3 Pack

I have purchased many “sets” of these road flares, for my car and also for my various family members to have in their own cars, in case any roadside emergencies occur. These are very well made (e.g., weather-proof, too); I am saying this, because I have bought so many and I have tested each and every road flare with batteries and cycled through all of the potential settings for the flashing lights, so that I could confirm that each of them works well, before I share these with other people. The magnets also work very well (the best test, at home, is to use the front door of your refrigerator, before you go out to your car, to test the magnet of each one), and these will adhere magnetically to the outside of your car very well — I recommend having several road flares, per vehicle, so that you can attach individual flares lights to various locations on the outside of your car: To the top (roof) of the car, both L & R side doors, 1 on the front hood, & 1 on the rear trunk (or back tailgate if you have a station wagon or SUV or pickup truck). I also recommend buying this particular set, because the purchase includes the large, orange carrying / storage case, for keeping the road flares stowed away (together) inside your car (or your trunk), and I prefer to purchase this brand, because of the large carrying case which can accommodate more than the original 3 road flares. What I mean is this: I purchased these road flares in such quantities that I prefer to have more than the original 3 flares in this larger, orange storage case, and so this is why I bought several sets at at time, so that each, orange storage case could have 5 flares inside of each case.I wish that I had had these road flares in my car, when I experienced 2 bad crashes which were both caused by other drivers. First, my 11 year old Honda Accord had just reached 130,000 miles, the day before, and, then, on April 15, 2012, my car was rear-ended and destroyed by a negligent driver (i.e., the entire rear trunk was smashed so badly that the trunk was collapsed up to the rear window, and I sustained a bad whiplash injury to my cervical vertebrae. I began physical therapy immediately. Then, my new car (purchased on May 16, 2012) was crashed into on the Right, front bumper and headlight, by a negligent, Hit-And-Run (probably drunk) driver in an SUV on the highway at 65MPH! My car was hit on the Right front bumper and headlight and driven off of the Left side of the highway, and the entire Left side of my car was scratched up, after the impact with the metal guard railing, in the middle of the median, between the 2 highways — I will never forget it: The date was Friday, June 8, 2012, and I was driving on I-84 Eastbound in NY State in the far Left lane, and my new, 24-day old Honda was hit on the Right front bumper (SUV tire tracks up and over the Right front corner and bumper and headlight of my car) and I swerved off the Left side of the highway to avoid the initial impact and crash. The front axle was so bent up that I had to have my car towed from NY state, back home to DC. Anyway, regarding these 2 car crashes: I wish that I had had these road flares in my car(s), at those times, because the highway crash occurred right after 9:00PM, and it was pitch black outside at night, and I was on the Left shoulder of the highway with traffic zooming by my damaged car, near the “fast lane,” and all that I had flashing were the Hazard lights on my car. These road flares are much brighter and visible at night, than regular Hazard flashers on the front and back of our cars, and I would recommend that you put at least 2 of the road flares on the top of your car. I highly recommend these road flares for you and your family, because (as I have described herein above), anything can happen unexpectedly in traffic or on the highway at 65MPH, and these road flares will be very useful to alert others of your damaged or immobilized car on any roadway — or the shoulder if you are changing a flat tire (at night). Good luck to everybody, and I hope that you do not have to use these, but, if you do, you will be more protected than if you did not have these road flares flashing on the sides and top of your vehicle(s).

I can't comment too much on the intricacies of these little guys, but I will say that in the times that I have used them, they have worked very well. The battery has held up as long as I have needed them to. My tire blew up on the freeway, in the middle of nowhere, at night, so I put some of these up the road a little bit as a warning to oncoming traffic, that I was there, and stuck one to the back of my car so they could see it at night, while I changed my tire. They are pretty bright, at night you can see them from quite a distance, and during the day, they may not work for getting attention, but I am sure you could still see the light. I took these on a hike through the back woods of Yosemite, in case of something awful happening, which looking back on was a bit overkill, but hey, at least I had flares if I would've needed them. I have hooked them to my friends bags during late night hikes, so I can see them from a distance, there is even 3 little white LEDs on the face of the device that can be used as a flashlight, and I have used that in my tent as a tent light, or held it in my hand to make sure I don't step on an angry snake or something.I keep them in my car when I am not doing anything super adventurous, and they hang out in my trunk, in their little orange back, perfectly happy when not in use.Overall: No complaints yet, but I haven't actually needed to use them too much, thank god. But every time they have been used they are the perfect solution.TL;DR Great little light disks, perfect for what I needed them for.

These roadside emergency lights seem plenty bright, and tough enough to do the job. I prefer these lights to use instead of flares, but have both just in case. I like the magnet on the back, and the light alternatives are numerous and should get attention from other drivers quickly. Don't know how long the batteries will last, so will likely change them at least once per year no matter if not used. Will most likely get a set for several family members. Very easy to use.Update, as of Jan 2020, I purchased another set for a family member. They saw the value of having the lights, even if they also have flares. The flares burn out fairly quickly, while these lights can go for hours if needed.Update 9-15-19, just received a second pack of these roadside lights to supplement any potential use of flares. The idea being that flares have a more limited time frame to produce lighting along the road.Update 10-5-19, I have ordered more of these for my family. I think they are so easy to use that my friends and family should just keep a pack in the vehicle at all times.

First when you install the your batteries it says unscrew 3 screws, problem is there are only two screws. It next tells you to open the upper tab by pressing with a screwdriver. This is not and easy task since the tab is tight and if the screwdriver slips you could be injured.I would snug the screws upon reinstalling them so you don't strip the screws.If you needed to replace the batteries in the dark; it would be impossible. So their statement the batteries are an easy installation is not true.However the product works perfectly and is well made. Easy to use. The lights are bright in dim light. The price is excellent.

These are actually great. They're very bright. The magnet and hook are great ideas and work really well. We tested them at night and you can see them from a long ways off, especially when they're set to blink. Heck, they even double as an extra flashlight. The little bag... kind of a waste. There are a whole bunch of different settings that affect how they behave and, I suspect, their battery life. The only concern I have is the battery, but I didn't want to burn one out testing it. I'll turn one on regularly to validate their shelf life, but overall, I'm very pleased. I'm buying another set for my wife.UPDATE: 2nd set purchased for the wife and put in her car. My son also purchased a set for his car. Everyone who tries them out, loves them. Fantastic safety device.
