Operation of Lights
Although your vehicle’s lighting system (headlights, parking lights, fog
lamps, side marker lights and taillights) meet all applicable federal
lighting requirements, certain states and provinces may apply their own
lighting regulations that may require special attention before you operate
these lights. For example, some jurisdictions may require that you operate
your lower beam lights with fog lamps at all times, or that headlights be
turned on whenever you must use your windshield wipers. In addition,
most jurisdictions prohibit driving solely with parking lights, especially at
dawn
or dusk. It is recommended that you check with you own state or
provincial highway authority for applicable lighting regulations.
