BATTIFE 4 Pack Traffic Cone Flasher Warning LED Light, Roadblock Lamp 360 Degree Visible with 3 Flashing Modes for Collapsible Traffic Safety Cones, Parking, Camping and Emergency

Ordered two of these. Opened one up and the spring at the bottom of the battery compartment that connects the two AAA batteries in parallel circuit was loose. No big deal. Just will have to carefully position the spring when installing batteries. The second unit's spring was properly attached at the bottom of the battery compartment. My main concern is that these units are really cheaply made. They are also not very bright, although in the dark of night when they probably will be used they may be adequate. I wouldn't have purchased them if I had had an opportunity to examine them first. They work but could have been made better.

The flashers were junk.I put batteries in when it arrived and they worked when tested.A few months later when I first needed to use them, they fell apart. They would not hold the batteries. One of the two could not be made to function.Junk.

Nice compact size, construction seems OK. Put batteries in and the flasher is very weak. You can barely see it on a cloudy day, I'm sure it's invisible on a sunny day. Maybe at night it works marginally well... haven't tried them at night yet. Good concept - needs brighter LED chips on board. Different flashing modes are nice however.

Not very bright for safety. Disappointed!

These lights work as advertised.PROsThey are bright and flash well. I bought 4 of these to place on my traffic cones. They slipped right in as if they were part of the cone.CONsOnce turned "ON" and set for flash mode you select they will continue to flash 24/7 even in daylight which you cannot see them. They take 2 AAA batteries which when turned "ON" will drain those batteries in 4 to 6 days. Some will not last 3 days. I tried new batteries and in each case 5 days was the most I could get.WHAT is needed for a fix.The flash should have 2 AA batteries or larger and a sun sensor to turn off in daylight. I think if these modifications were made these lights would be almost perfect.The reason for the 1 star is only because of the battery drain issue. Too expensive for any long term use.

The light output was very dim and 1 of the 2 lights didn’t work at all

They do work. But they are small and the handle part that the batteries go in to falls off kinda easily I’m sore. They are great for some things but for my work pulling hoses and lines around the cones if the cone gets hit a bit hard the batteries fall out

Great idea/concept, however the lights are a poor design with design flaws. In the photo it appears that the LED light cells are on the red platic dome, however they are located flat on the circuit board and not on the dome. Therefore, the two LED lights, which are bright, are pointed straight up with no redirection of the light. This results in the light being bright if looking straight down from the sky but very dim if looking from the side like a driver or pedestrian. Also, the button is located where it sits on the cone and if touched or bumped the button is pressed by the cone turning the light off. I returned the product but could be interested if design changes are implemented.
