I really like this Twinkle Star emergency roadside LED strobe light and I think it is going to be a great supplement to emergency road flares alone. I tried it outside at night and found it to be very bright and has a strong enough magnetic base to hold it onto my car even with the cover on! (I was too lazy to remove the car cover). I also really like the compact case and two bases for standing it upright on the ground. Hopefully, I'll never have to use this, but my only concern is that if I do need it years from now, will the batteries still be good? Also, how long will they last in an emergency and keep the strobe going? I'll have to make a note to check the batteries once a year and keep the flares just in case.

First off, the visibility is impressive. They emit a bright red light that stands out significantly compared to traditional puck-style emergency lights. I tested them against some Wagan FRED lights, and the Twinkle Stars were noticeably brighter and more effective from a distance. Their height—about 8 inches when placed in the included stands—also gives them an edge, especially in snowy conditions where low-profile lights might get buried.The kit comes with four flares, which is great value for the price. They’re packaged in durable cases that fit easily into your car's storage, making them convenient to keep on hand. Each flare has a simple button to toggle between flashing red, constant red, and a white flashlight mode, which is user-friendly.One feature I particularly like is the strong magnetic base. This allows you to attach the flares to your vehicle or other metal surfaces, which is handy if you need to set them up quickly without worrying about them blowing away or getting knocked over.

Good for the car on dark nights for safety

I purchased these just in case I ever needed them, and last month I had to use them at the scene of a serious vehicle crash, unfortunately. Cars slowed down considerably more after deploying these lights. They're very bright and are perfect to use as torches too.

These emergency lights are pretty descent. They are compact and comes in a convenient storage box. The light is bright enough and will provide a visibility in the night if you had to pull over or stop on the shoulder.I personally bought it as a safety device to use in emergencies (which can happen, but not too often). There were not too many alternatives on Amazon for that price (I mean it’s all the same crap from Alibaba). Given that, here are my pros and cons.Pros:- compact size and flat box they are coming provide a good option to store it in a trunk or tool compartment- I love fireworks, but not sure flares are good in dry California woods. These lights are good alternative to flares- they have white light option which can help if your EDC and working flashlights (you have both, right?) died- batteries. It’s the most reliable solution, just make sure to keep a pack of AAA batteries in your car, and you will always have a light.- they are cheap. For something that most of the time will be stored in the trunk without usage it’s a good value for moneyCons:- they are cheap. No one can guarantee that they will light up when you really need them- they are small and lightweight, which can become a problem in harsh conditions- the stand is not very reliable, not sure they will withstand a wind blow from a passing by truck- these lights don’t seem to be water or even splash proofOverall: I keep one set in my and one set in wife’s cars along with other flashlights and emergency tools. Since it’s not the only one source of light in both cars, I’m ok with the quality and find it to be good for money.PS. Even a small problem or a flat tire in low visibility conditions can easily escalate to a nightmare and cost a life to you or others for a very silly reason. Please, invest in your own safety: even if you drive only around your neighborhood, always have in the car a flashlight (s), emergency lights, hi-vis vest, fire extinguisher, etc.

Better visibility than the puck/disc style LED emergency flares.I've had a set of the Wagan FRED (Flashing Roadside Emergency Disc) 'hockey puck' style lights for 2-3 years now. I haven't personally needed to use them, but have given the 3-pack sets to my neighbors as gifts, and they just recently used them while changing a flat on the side of a busy highway.They reported that the Wagan FRED lights worked well, just using the magnetic bases to attach them on the sides and back of the vehicle, as other motorists moved a lane over when they saw the flashing lights as they approached.I recently saw the listing for these Twinkle Star LED flares and was curious about how the design compared, so I ordered a set (they seem to be a generic design, sold under various names, but look identical aside from the label. At the time of purchase, this Twinkle Star Amazon listing for 2 pairs for $29.99 was almost half the price compared to the other listings for 1 pair for about $25).Upon delivery, I installed the included batteries and both pairs worked just fine with no issues. These flares come boxed in pairs, with 2 flares and 2 stands in their own hard case (with this listing consisting of 2 cases with 4 total flares). The cases are small enough to slip into the pockets behind the seats of many vehicles.There is a single button to turn them on and cycle through the modes (flashing red, constant On red, constant On white flashlight, Off).I set 1 pair of these, and 1 pair of the Wagan FRED lights on the pavement in their strobe modes and then headed off down the street to see which was more easily visible from far away.WINNER: The pair of Twinkle Star LED flares. They flash a bright red that's brighter and more visible from a distance than the Wagan FRED lights, and the height is an advantage for visibility. The tops of these flares light up a bright red, but like the puck style lights, they also light up the ground immediately around them.Overall, they were much more noticeable at a distance than the Wagan FRED lights.Another consideration for folks in the snowbelt: when it's snowing hard, and/or there's already snow accumulation on the ground, this design that has these sticking up 8" above the ground when placed in the included stands, is a distinct advantage for visibility over the pucks that are 2" high when set on the ground.I'm not sure how weather/waterproof either design is, but when placed in the stands, the base of the flares is ~1.7" above the ground, i.e. the puck style flares would be mostly submerged at that point if standing water was a concern.The bottom of these flares also have a pretty strong magnet on them (which is how they stick/attach to the stands), which means you can attach them to the body or roof of a stranded standard steel bodied vehicle (not so much for the carbon fiber or aluminum exotics), or even use the magnets to attach them to metal guardrails and mile markers for added height etc.Since I already have the Wagan FRED lights, they'll be along for the ride too, but now I'm getting a set of these Twinkle Star LED flares for all the vehicles. If I had to choose between them, I'd get these.P.S.As with ANY piece of electronic equipment I deem important (depending on these to prevent inattentive drivers from turning me into road pizza, qualifies), I highly recommend ditching the included batteries and using Energizer Lithium Ultimate AAAs instead (each flare uses 3xAAA batteries). The Lithium Ultimates won't leak and render these useless when needed, and Lithium Ultimates will work down to -40f, where alkalines don't work very well below about 15f.The Wagan FRED lights have had the same Lithium Ultimate batteries in them for the past ~3 years, left in the vehicle in temperatures ranging from 110+f to -14f, and still work just fine.I'll post an update in about 12 months as I periodically test these to see if there's any parasitic drain that may cause the Lithium Ultimate batteries to be drained flat when left in them.

Put the batteries in but sadly one did not work... no replacement offered, just a refund
