Patent ID: 7233111

Claim:
An illumination device comprising: a wire harness including a first conductor, a second conductor, a third conductor and a fourth conductor which are electrically separated from one another; a plurality of illumination portions; a mode-changing switch for changing a light-emitting operation mode of said plurality of illumination portions, said mode-changing switch electrically connected to said second conductor and said fourth conductor, and switched between a short-circuited state in which said second conductor and said fourth conductor are electrically connected together and an open state in which said second conductor and said fourth conductor are electrically disconnected from each other; a switch, provided in each illumination portion, including a first electrical contact, a second electrical contact, a third electrical contact, and an electrical contact member which is movable between a first position where said electrical contact member is disposed in contact with said first and second electrical contacts to electrically connect said first and second electrical contacts together, and is disposed out of contact with said third electrical contact and a second position where said electrical contact member is disposed in contact with said second and third electrical contacts to electrically connect said second and third electrical contacts together, and is disposed out of contact with said first electrical contact; a light source including a first electrical contact, and a second electrical contact electrically connected to said second electrical contact of said switch; a first electrical terminal electrically connected to said first electrical contact of said light source and said first conductor; a second electrical terminal which is electrically connected to said third electrical contact of said switch and said fourth conductor, and can be electrically connected to said second electrical contact of said light source when said electrical contact member of said switch is brought into said second position; and a third terminal electrically connected to said first electrical contact of said switch and said third conductor.
