Blazer International 195C6350 LED Magnetic Emergency Safety Light – Red, Battery Powered, Dual Flash Modes, High-Visibility Warning Beacon for Roadside, Construction, and Farm Use Automotive Accesory

These will get attention wherever you need it I bought 2 and they will go on the back end of a dump trailer. The instructions in the package are confusing and really no help you have to take out 4 small screws to access the battery area on the back side to install your own 4-AA batteries that are not included. Then with a single press of the yellow button on the back you go from solid bright light to flashing to off. With the strength of the magnet wherever you place them I feel confident they will not move. Overall the light seems well made and weather proof and can I definitely recommend!

I bought this item to disassemble to get the red lighting out to use in a deer blind. However, when it arrived. I was amazed at the quality. So instead of using it for that, I ordered a battery powered LED light string. I then took this light to the shop and I use it for exactly for what it was designed. I attach it to my tractor or implement when I am traveling on the road. Shows up very well and the magnetic base holds it tightly (I still tie a cord around it just in case the no-shocks tractor ride gets too rough). This replaced my older emergency light because it is brighter and a little larger.

I keep these in my truck, always ready to help law enforcement at crash scenes.

The lights are extremely bright and should be visible from quite a distance. I haven't needed to use it in an emergency yet - thank goodness - but I think these will do the job nicely. The magnets are strong enough to adhere to my vehicle, and a little care should ensure the paint is not scratched. As others have commented, it is a pain to work on when changing batteries. I had to take it completely apart to recover one nut that dropped into the housing, and the (housing) screws were recessed so deeply that my regular screwdriver shaft could not be inserted. I have now seated the nuts with a drop of super glue and should not have to deal with that again. Also, one LED appeared dead on arrival, but it turned out to be a loose connection. Since I had it apart anyway I was able to wiggle the bulb back to life. A spot of solder took care of that issue permanently. Note: I also bought an identical light in Amber, and had none of the above issues.

I'd steer clear of this product. I purchased two and only one worked. The other will not light up - out of box failure. I disagree with the reviewer who said the backing will not scratch your finish. There are two round, powerful magnets to hold the light to a metallic surface. But the magnets are housed in chrome-plated metal rings that are sure to scratch anything unless you are very, very careful. Also, the on/off button is nearly impossible to press with a normal sized finger. You'll need to use a pen point or something of similar size and hopefully you'll have something like that with you if needed on a dark night. Overall a very poor design and unreliable as well.

These lights are good stopgaps for the dead and broken taillights on my boat and utility trailers. The strong magnets hold them firmly in place, and they're bright enough to see even in sunlight. You do need steel to attach them, so you'll need to make sure your trailer isn't all aluminum. I liked being able to pop batteries in, attach the lights and go, without wiring. They won't replace turn signals, but they are more than adequate for illumination. They probably will get you to the trailer repair shop without being pulled over. There's also a flashing function, if you want to be even more careful.

The instructions are for a completely different product. They don't resemble this light in any way. There are 8 screws on the back of the light. To change the batteries you need to remove the 4 screws on the ends of the light. NOT the 4 screws that set lower on the light as you look at it from the back. In my experience, you'll be able to do this once or twice before the screws strip out the threads in the plastic base. Not impressed with the battery install at all. The light is bright and the strobe is nice. I'm putting it on a trailer for a hay rack ride tonight. I'll see how well it holds. Overall, seems rather cheap for the mondy

This is a very sturdy light, with strong magnets to hold it in place . The light uses 4 batteries, and the case is a bit difficult to open to put in the batteries; it would be a problem if your car broke down on a dark road with no lights and you couldn’t find a screwdriver . It needs to be made with an easier to open battery compartment, as I don’t like leaving the batteries in it all the time.

Bright,and good magnet.

Purchased two lamps to go on the rear of a trailer pulled by a slow moving vehicle. The magnets were strong enough to hold the lamps in position and were as bright as those on cars. Didn't require the flashing option, easy to select between the two. Very happy with the purchase.

Excelente

Got these for hauling overdimensional loads at night. They have bright lights with multiple modes. The magnets are 2 large style, which hold into steel surfaces very well without other securement.

Work well as advertised. Good quality, good seal
