Hi Dylan,
Our Landmark has a wall type of light switch for the electric side of the water heater. When turned on the switch lights up.
If it's not on, check the circuit breakers first. Make sure the rocker switch on the outside of the water heater is turned on. It's also possible there could be a loose connection at the back of the switch.
We have a detailed
Water Heater Usage Guide, and also a Water Heater
Troubleshooting and Repair Guide if you need additional information.
