There are two common types of trouble lights: AC powered and battery powdered.
Most 110-volt AC powdered trouble lights have a grounded outlet for plugging in
other powered tools such as drills. You may get one with 16 gauge wire that can
use a 75 watt bulb. The 12-volt lights are ideal for outdoor or emergency
Sometimes it is quicker, easier, and more effective to spot something
with a flashlight than with the standard trouble light. Always keep a good
flashlight in your tool box.
