Markstor 6-Pack LED Road Flare Car Emergency Kit,Magnetic Base & Hook Road Flares Safety Light With 9 Flashing Modes,Roadside Flares Emergency Lights For Vehicles (6 Pack)

These new type LED road flares are very effective.They have many different strobe patterns so different patterns can be used in each unit in emergencies to attract and focus attention.Yellow and red with a flashlight mode.Strong magnet allows marking a car in several places and will probably adhere while towing.LED effectiveness should give a battery life of more than 8 hours- sufficient for an overnight or long use.They would be essential if stranded by snow to mark an occupied car for rescue.They have a rubber-like seal which would keep them working in rain or snow and aboard a boat in heavy weather- underwater doubtful but possible maybe shallow.Being a six pack enables multiple use at longer distances from a problem site and makes them cheap enough to leave behind if required (cheaper than a burning flare.)Takes 3 aaa batteries each.PREPAREDNESS:These are essential pieces of emergency equipment for those who are prepared.Just put in your calender a reminder to replace batteries yearly. It's not the battery life but the possibility of corrosion for alkaline batteries left in any unit for a long period. Carrying spare batteries is a good idea- the unit comes with a small screwdriver remove screws.But I wouldn't let them be empty of battery because installing batteries takes time that might not be available in an emergency.

bright, strong magnet, stainless screws

Attached video is using two in my garage. Many Programs. Tested and re-tested all six purchased. All Worked Perfect. Just do not store the batteries in the unit as they will leak and damage it. I put my batteries in a Ziploc bag and stored them with the unit in the included case along with the included stubby screwdriver.Very Bright, attention grabbing to warn other drivers to proceed with caution. Could also use for camping, home emergencies to attract police or fire, etc. In daylight it does look like a toy, but at night it comes alive with the bright attention warning lights. Strong magnet on the back is very nice to attach it to the car. Especially if you have to drive slow with a donut tire, (because of a flat primary) you can place them on the top of the trunk to warn others as reasoning for the slow speed until you get to a safe location. This, of course works in conjunction with your auto emergency flashers.

Very bright, lots of flash pattern to choose from, seem durable. only thing is if you turn it on and drop it they shut off ? not a big deal they turn right back on.Thanks, John...

Great set to put in the truck. Convenient case to keep them all together. Each one has a solid plastic and rubber finish. Easy to turn on and off. Simple to find the light pattern that you need. The hook and the magnet are a great addition for multiple uses. Each one is the size of a hockey puck but maybe a bit thicker. Each one takes 3 batteries. They install is a little tricky due to it only fitting one way. Takes 2 bolts to pop it open with the smallest screwdriver I’ve ever seen that fits in the storage sleeve and is included. When closing these up make sure everything is aligned. That makes them waterproof. Overall a great addition to the truck for added safety.Good price for what you get. Just make sure you order enough batteries.
