Digital Volt Meter AKA  DMM Digital Multi Meter

The advantage is no needle on the meter to get damaged, usually better 
accuracy and no load placed on the circuit you are measuring.

The down side is since the meter does not load the circuit, stray voltage 
will make you think the circuit has full power but it does not.  If you are 
measuring battery state of charge, a oxygen sensor or other computer car 
sensor, 
the DVM is better.  If you are just trouble shooting a wiper circuit, a test 
light is better because it load the circuit.
