• Quickly and easily assess if there is power within the 7-way connection between the tractor
      and trailer
    • LED indicator easily identifies which circuit is not receiving power
    • Designed for integration into the electrical system at the nosebox*
    • Eliminates the immediate need for a continuity tester

*Additional tools (not included) may be needed for installation. Phillips is not liable for damage caused to any nosebox when installing for retrofit.

Important Note: This product does NOT eliminate the need to perform a pre-trip inspection. It only confirms an electrical signal from the tractor to the trailer. It does NOT check the lighting and wires on the trailer. Additionally, it does not confirm if there is significant voltage to power a circuit. It is an indication of continuity only.
