(a) Any 2 or more lighting devices and reflectors may be combined into one shell or housing except as stated below, provided that the requirements for each required lighting device or reflector are met and that neither the mounting nor the use of any nonrequired lighting device is inconsistent with this article in any respect:
(1) No turn signal may be combined with a headlamp or other lighting device or combination of lighting devices capable of producing a greater intensity of light than the turn signal when the turn signal is operating.
(2) No turn signal may be combined with a stop lamp unless the arrangement of switches or other parts is such that the stop light is extinguished whenever the turn signal is in use.
(3) No clearance lamp may be combined with a tail lamp or an identification lamp.
(b) Any lamp or lamps combined in the same shell or housing with a turn signal may be turned off by the same switch that turns the signal on for flashing, and turned on again when the turn signal as such is turned off.
