If your LUELLI LU-TK LED light isn't illuminating after you've prepped it, several factors could be at play. First, check the battery. Even if you've removed the plastic tab, the battery may be drained. Replace or recharge the battery according to the LUELLI LU-TK's user manual. Next, confirm the light is correctly connected. Ensure the LED light is firmly attached to the mouth tray and that all connectors are properly aligned. A loose connection can prevent it from working. Should the issue continue, please contact Luelli customer support for further troubleshooting assistance; they can offer specific guidance for your LU-TK LED light.
