Voltage Reducer - 12 To 6 Volt - 1 Amp Max.
Reduces 12 to 6 volts, designed for gauges. Comes with detailed instructions.
1 is needed per gauge, and actually mounts onto the gauge itself, allowing you to run several in a row. This enables you to use original 6 volt gauges or sending units, while the rest of your vehicle is still 12 volt.
NOT required for Amp gauges which are not voltage-sensitive.
Price for One.
