Using this Chef neon indicator light is easy. First, make sure the power to your stove or equipment is turned off. Then, connect the 150mm wires with 6.4mm female flag spade terminals to the appropriate terminals in your device. Once connected, you can turn the power back on, and the red light should indicate the status of your equipment. When it comes to maintenance, keep the light clean. You can use a soft, dry cloth to wipe it. Avoid using any abrasive materials as they might scratch the light. Also, if you notice any issues with the light, such as it not lighting up or flickering, turn off the power immediately and check the connections. If the problem persists, it might be time to replace the indicator light.
