The motor housing has a top portion, a bottom portion opposite to the top portion, and side walls disposed between the top and bottom portions. A handle housing is connected to the bottom portion of the motor housing. A spindle is operatively connected to the motor. A first light assembly is disposed on a side wall of the motor housing. ## Claims ### Claim 1 An electric power tool comprising: a motor; a motor housing at least partly encasing the motor, the motor housing having a top portion, a bottom portion opposite to the top portion, and first and second side walls disposed between the top and bottom portions; a handle housing connected to the bottom portion of the motor housing; a spindle operatively connected to the motor, the spindle being rotatable about a rotational axis; an end effector operatively connected to the spindle; and a first light assembly disposed on at least one of the first and second side walls of the motor housing and configured to illuminate a region adjacent the end effector. ### Claim 2 (depends on 1) The electric power tool of claim 1, wherein the first light assembly comprises a board having at least one portion thereof being substantially parallel to the rotational axis, and a side view LED mounted on the board. ### Claim 3 (depends on 2) The electric power tool of claim 2, wherein the side view LED has a height and width, the height being larger than the width. ### Claim 4 (depends on 2) The electric power tool of claim 2, wherein the side view LED is installed on the board by moving it in a direction substantially perpendicular to the at least one portion of the board. ### Claim 5 (depends on 2) The electric power tool of claim 2, wherein the side view LED emits some light substantially parallel to the rotational axis. ### Claim 6 (depends on 2) The electric power tool of claim 2, wherein the side view LED emits some light substantially perpendicular to the at least one portion of the board. ### Claim 7 (depends on 1) The electric power tool of claim 1, further comprising a second light assembly disposed on the other of the first and second side walls of the motor housing. ### Claim 8 An electric power tool comprising: a motor; a motor housing at least partly encasing the motor, the motor housing having a top portion, a bottom portion opposite to the top portion, and first and second side walls disposed between the top and bottom portions; a handle housing connected to the bottom portion of the motor housing; a spindle operatively connected to the motor, the spindle being rotatable about a rotational axis; and a first light assembly disposed on the motor housing, the first light assembly comprising a board having at least one portion thereof being substantially parallel to the rotational axis, and a side view LED mounted on the board. ### Claim 9 (depends on 8) The electric power tool of claim 8, wherein the side view LED has a height and width, the height being larger than the width. ### Claim 10 (depends on 8) The electric power tool of claim 8, wherein the side view LED is installed on the board by moving it in a direction substantially perpendicular to the at least one portion of the board. ### Claim 11 (depends on 8) The electric power tool of claim 8, wherein the side view LED emits some light substantially parallel to the rotational axis. ### Claim 12 (depends on 8) The electric power tool of claim 8, wherein the side view LED emits some light substantially perpendicular to the at least one portion of the board. ### Claim 13 (depends on 8) The electric power tool of claim 8, further comprising a second light assembly disposed on the motor housing.
