Rotary power tool

A power tool comprising:

• a tool housing;
• an electric motor disposed within the tool housing;
• a first printed circuit board assembly configured to selectively supply electric current to the electric motor, causing the electric motor to activate and drive a tool element;
• a battery receptacle configured to support a removable battery pack, the battery receptacle having a battery terminal block electrically connected to the battery pack to supply electrical current to the first printed circuit board assembly;
• and
• a light assembly supported within the tool housing and configured to indicate a state of charge of the battery pack, the light assembly including
• an auxiliary housing,
• an auxiliary printed circuit board supported within the auxiliary housing, the auxiliary printed circuit board having a plurality of light-emitting diodes (LEDs) mounted thereto, and
• a plurality of light pipes extending through the tool housing and having respective distal ends that are visible from an exterior of the tool housing, wherein the light pipes are positioned adjacent the respective LEDs to transmit light emitted from the LEDs to the exterior of the tool housing.

A light emitting diode fuel gauge assembly configured to display a state of charge of a battery pack, the light emitting diode fuel gauge assembly comprising:

• an auxiliary housing;
• an auxiliary printed circuit board supported within the auxiliary housing, the auxiliary printed circuit board having a plurality of light-emitting diodes (LEDs) mounted thereto;
• and
• a plurality of light pipes configured to extend through a tool housing and having respective distal ends that are configured to be visible from an exterior of the tool housing, wherein the light pipes are positioned adjacent the respective LEDs and are configured to transmit light emitted from the LEDs to the exterior of the tool housing.
