Our voltmeters are a practical and reliable solution for monitoring voltage levels in your vehicle. With a gauge that reads from 8.0 to 18.0 volts and displays voltage to the nearest 0.1, you can easily keep track of your electrical system's performance. Available with a red, blue, or green LED display and a chrome or black bezel, these voltmeters are customizable to suit your preferences. Made in the USA and designed to fit most Peterbilt models 2005 and older, these voltmeters are a must-have for any vehicle owner. Please note that they do not fit Kenworth models.
