Headlight High-Low Beam Lever; Windshield Wipermasher - Buick 1994 LeSabre Owner's Manual

If you have a trailer towing option with added wiring for
the trailer lights, a different turn signal flasher is used.
With this flasher installed, the signal indicator will flash
even if a turn signal bulb is burned out. Check the front
and rear turn signal lights regularly to make sure they
are working.
Operation of Lights
Although your vehicle's lighting system (headlights,
parking lights, fog lamps, side marker lights and
taillights) meets 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 fog lamps only when your lower beam
headlights are also on, 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 your own state or
provincial highway authority for applicable lighting
regulations.
Headlight High-Low Beam
BRIGHT
To change the headlights
from low beam to high or
high to low, pull the turn
signal lever all the way
toward you. Then release it.
When the high beams are
on, this blue light on the
instrument panel also will
be on.
