Washington-based A-1 Truck Repair has launched its new A-1 Quick Check to help diagnose light problems without having to remove the junction box cover and testing wires.


To use the new device, you look through a clear cover on your junction box to see if the LED lights are lit. If they are lit, then the problem is down the electrical line past the junction box.

The A-1 Quick Check includes the circuit board, nuts, washers and instructions.
