If your LUELLI LU-TK light isn't illuminating after removing the battery tab, several factors could be at play. First, check the battery. Ensure it has sufficient power; replacing or recharging it according to the manufacturer's guidelines is a good first step. Secondly, confirm the light's connections. Make certain the LUELLI LU-TK LED light is correctly attached to the power source or device, paying special attention to alignment and secure placement within the mouth tray. If these steps do not resolve the issue, please contact Luelli customer support for detailed troubleshooting guidance.
