Review on 📈 Gasher Energy Saving Industrial Electrical and Controls & Indicators: Mounting Indicator for Efficient Energy Management by Walter Velasquez

These are headlights and they worked, we fitted them to the tractor to indicate when the implement solenoids are energized. They've only been around for a month so I can't say how long they will last, but it looks like they will. They give off a moderately bright light that is visible in daylight and not too overwhelming at night.
