Garage Monkey Engineering LED Road Safety Flare Roadside Warning Safety Flare Kit for Vehicles & Boat | 4 Beacon Disc Pack

I bought this 4 pack because of excellent reviews and best per unit price. Turns out not a bad choice, and I'm adding another 5 star review. The rotating lights mode might be the most useful during road emergencies, so I tested it with 3 eneloop batteries to see how long it actually lasts. After 10 hours, batteries were mostly dead but lights were still flashing as bright as with fresh batteries. Very impressive. Lights are very bright and should be seen even in daylight.It comes with instructions how to open the back plate to install batteries. Back plate is installed pretty tight for water proofing. Without reading the instructions I would probably have tried to pry it open using a screwdriver or something and damage the housing. In case you are wondering - there are two tabs in the 2 o'clock and 10 o'clock location to give you some leverage to pull the back plate off.Also interesting that seller mentioned not to use regular or cheap alkaline batteries because they eventually leak and ruin the device. That's my experience too. Even "good quality" duracell and Costco kirkland batteries are prone to leak after certain years. Energizer max and Energizer lithium primary are the only two types don't leak, or try LSD NiMH rechargables.

These are great lights! Work better than described actually! Was so pleased with the first set I ordered another.Update 8.17.18 I used zip ties and placed two of these on the back of my 14' Hobie fishing kayak as it sticks out the bed of my truck quite a ways. At a top light a State Trooper stated he thinks they are great and much better than just a simple red flag or shop towel he sees so often. I did not remove them while using the kayak and one took on a bit of water, but after I drained it and dried it out a couple of days it worked fine. I inquired from Garage Monkey (seller) if they had waterproof ones and was advised these should do just fine. I explained one got a bit wet but works fine and I was going to apply some silicone sealant around the screws and the magnet area to test them again. Rod, the owner advised me he has sent two free replacements at no charge!!! Amazing and Outstanding customer service that is far above what anyone would expect!

I have been looking at this for a long time and finally decided to order a set to test them out before ordering sets for all the vehicles. When I received them, I was very pleased with the initial feel of quality. They seem pretty rugged and well sealed to keep water out.Con: To visually steer traffic around you, they need to "spin" in a clockwise direction, however, these "spin" in a counterclockwise direction that could visually steer someone into the back of your vehicle instead of around it. Of course, if you are buying these in a European country, they are perfect. This can easily be overcome by placing them upside down, but if you need to place them on your vehicle, you lose the use of the magnet. I would think that this would be an easy fix on the logic board for the factory.

I have no idea how well these will work. To my surprise I find that these do not come with batteries. I bought 12 so now I will have to go out and buy 36 AAA batteries. Very disappointing not to have them work right out of the box.

This product of the LED ROAD FLARES , BY GARAGE MONKEY are amazing. My husband and I travel on a major highway in Missouri and after reading and viewing the video I was convinced we needed to keep in our cars. Much to our surprise Missouri had a snow storm which halted miles of traffic from stalled automobiles, and autos not being able to drive on the snow packed 8 plus inches of snow. We had our flares in our 4 wheel drive. Although not needing because of the capacity of our truck. Thinking the dangers of many being pushed the LED ROAD FLARES, BY GARAGE MONKEY would of been of great help for the safety of individuals helping others in despair. If my husband was younger he would of been one of those individuals plus using the flares for safety. Please everyone reading this review take the time to look at the video. This may save your life and many others. I have 3 children with grandchildren and the safety for them to have in their vehicles are peace of mind for Nana, and Poppa D., Thank you Garage Monkey Your Flares could been seen from a distance for safety. As we all know when we see flashing lights regardless tow trucks, police we slow down for the safety of the individual on the side of the road., Take precaution for your safety.
