The Marantec 161388 Warning Light Kit is an original accessory designed to add a highly visible visual alert to compatible Marantec garage door openers. When connected to the operator’s accessory terminals, the warning light flashes to signal door movement or pending motion, helping alert pedestrians and vehicles in and around the doorway. This upgrade is ideal for residential and light commercial applications where an external visual indicator improves awareness beyond the opener’s built-in signals, and it serves as a direct replacement part for existing Marantec warning lights that need service.
Engineered for select Marantec operators, the 161388 kit integrates with the opener’s control logic so it activates during door operation and supported safety functions such as timer-to-close. Typical installation involves mounting the light in a conspicuous location and running low-voltage wiring to the opener’s accessory connection points; always follow the instructions provided with your specific Marantec operator and disconnect power before wiring. For best results, install in a location with clear line-of-sight to the area you want to warn, route wires away from moving parts, and verify that your opener model supports an external warning light output. This Marantec-branded accessory is a dependable choice for owners seeking a compatible replacement or a safety-focused upgrade to their garage door opener system.
