Review on 🔦 Fortune Products PL-300AJ Ultra Bright Amber LED Safety & Emergency Beacon Light with Magnetic Bottom - Battery Powered and Effective! by Donald Phillips

I bought it with full intention of taking it apart and modifying it right away. I bought it because the empty space in the middle (where the batteries should be) was enough for a small relay and a Raspberry Pi Zero. It was! I was able to turn light into an IoT device without much trouble. I wanted to share my experience here in case anyone else thinks about doing something similar.1. If you plan on taking the inside apart to get to the circuit board, 2 of the 3 screws holding the reflective piece are hidden under the magnets on the bottom. A little annoying because I originally wanted to leave the magnets intact for later hanging.2. The magnets on the bottom are glued very well. (Well, for anyone thinking of using it on a car, that should be reassuring!) I had to get out my heat gun to heat the magnet and soften the plastic rings around it, and then use a utility knife to to cut the plastic ring so I could put the lever under the hot magnet to gently pull it out. The end result was ugly, but that's why, so I didn't care. I destroyed the magnets by trying to remove them in other ways, so I just threw them away.3. Using a soldering iron, removing the battery connector was very easy.4. If you want to use a wall adapter you will need a 5V, 500mA power supply (minimum for light only, I bought 3A to power the light, Pi and a small speaker) with a 5, 5mm/2.5mm head. The gap under the block is about half an inch. So if you have a power supply with a straight plug or a large angled plug, the light will not sit flush. I had to buy 3 supplies before I got the one that allowed the light to sit flush. I made a very small notch in the base to allow the cable to pass through.5. There are three wires coming out of the female DC connector, 2 red and one black. If you're planning on connecting for another device (like I did to power the Pi), the two reds are your plus and minus. You need to use a multimeter to determine the polarity.6. Everything else was easy to manipulate with a drill or dremel.
