Headlamp High/Low-Beam Changer - Chevrolet 2005 Silverado 1500 Pickup Owner's Manual

As you signal a turn or a lane change, if the arrows
flash more quickly than normal, a signal bulb may
be burned out and other drivers won't see your
turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you signal
a turn, check for burned-out bulbs and a blown fuse.
See Fuses and Circuit Breakers on page 5-128.

An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the
turn signal and the message TURN SIGNAL ON will
also appear in the DIC. To turn the chime and message
off, move the turn signal lever to the off position.
