Classic Instruments SN11 Low Voltage Sensor Warning Light

The Classic Instruments SN11 Low Voltage Sensor is a critical electrical system monitoring component that alerts you to potential charging system problems before they leave you stranded. This sensor actively monitors your vehicle's electrical system voltage and triggers a warning light when voltage drops to 11 volts or less, giving you early warning of alternator failure, battery issues, or excessive electrical draw.

Key Features:

• Automatic low voltage detection triggers warning at 11 volts or less
• Versatile bulb compatibility - works with either the included LED bulb or standard incandescent bulbs
• Easy integration with Classic Instruments gauge systems or standalone warning light setups
• Helps prevent dead battery situations and electrical system damage
• Compact sensor design for simple installation in tight engine bay spaces

Essential for hot rods, custom builds, and classic cars where electrical system monitoring is critical, the SN11 sensor provides peace of mind by alerting you to charging system problems before they become roadside emergencies. The included LED bulb offers bright, low-power warning indication, while compatibility with incandescent bulbs ensures flexibility for period-correct restorations.
