Power tools are taught having a motor M1, a tool 1 coupled to the motor M1 via a tool holder 2, at least one light 4 disposed proximal to the tool 1, a switch 6 coupled to the motor M1 and the light 4, the switch 6 being capable of activation by an operator, a power supply 7 coupled to the switch 6,

Power tools are taught having a motor M1, a tool 1 coupled to the motor M1 via a tool holder 2, at least one light 4 disposed proximal to the tool 1, a switch 6 coupled to the motor M1 and the light 4, the switch 6 being capable of activation by an operator, a power supply 7 coupled to the switch 6, and a timer circuit 3 coupled to the light 4, the switch 6 and the power supply 7. Preferably, activation of the switch 6 causes the motor M1 and the light 4 to operate and the timer circuit 3 causes the light 4 to remain lit for a predetermined amount of time after either (1) the switch 6 has been activated or (2) the switch 6 has been deactivated subsequent to being activated. The timer circuit 3 can be, for example, a RC timer circuit 11 or a microprocessor 15. The light 4 may be an LED. The power supply 7 can be a rechargeable battery Ba.

[ What is claimed is:] [1.]1. A power tool comprising:a motor,a tool holder coupled to the motor,at least one light disposed proximal to the tool holder,a switch coupled to the motor and the at least one light, the switch being capable of activation and deactivation by an operator,a power supply coupled to the switch anda timer circuit coupled to the at least one light, the switch and the power supply, wherein the power tool is constructed such that activation of the switch causes the motor and the light to begin operation at substantially the same time and the timer circuit causes the light to remain lit for a predetermined amount of time after either (1) the switch has been activated or (2) the switch has been deactivated subsequent to being activated, wherein deactivation of the switch interrupts the power supply to the motor and causes the motor to stop operating.
