Using this red neon indicator light is easy. First, make sure your equipment is turned off and unplugged. Then, connect the spade terminals (either the 6.4mm or 4.8mm ones depending on your equipment's requirements) to the appropriate connections in your stove or other device. Once connected, plug your equipment back in and turn it on to see the indicator light work. When using the indicator light, always ensure the voltage is 240VAC to avoid any damage. Also, don't touch the light when it's on as it might get hot. For maintenance, keep it clean by gently wiping it with a dry cloth every few months. If you notice any issues like the light not coming on, check the connections first. If the problem persists, contact our customer service for further assistance.
