Review on 🦊 FoxFire 6004000 Portable Signal Range by Ron Long

I use these as safety lights on a boom lift truck that works in traffic at night. These lights are bright and the magnet works very well. A set of batteries lasts for about 15-20 hours of operation. I bought them in November (now April) and have used them for several hundred hours, they have served their purpose, however their quality has deteriorated over time. The magnets have lost their hold and are only supported from below (on a vertical beam made of painted steel). One was knocked over for falling, and the other had half its LEDs burned out after being dropped half a dozen times. This reflection of our construction site is more than just quality. I think the rule of thumb is that they work fine for a few months, but you'll need to replace them from time to time. You can't argue with $20.
