Compact Design: Measures roughly 4-1/8″ wide × 2-1/2″ high × 3/8″ deep, ideal for flush or surface mounting
Low Voltage Warning: Built-in alert for low system voltage (Airstream recommends 8 V as the lower limit for reliable detection)
Hardwired Installation: Connects directly to trailer power; includes an in-line 1A fuse
