Left and Right Turn Telltales

activated and blinks in time with the out-
side turn signal lamps. An audible signal
also sounds in time with the telltale. A sin-
gle short beep is heard when the telltale
lights up.

5th Wheel Lock Telltale
This telltale will light up yellow when the
pneumatic switch for the 5th wheel slide
lock is turned on. It will stay lit until the
switch is turned to the off position again.
See the 5th wheel uncoupling section on
page 280 for correct use.

Wheel and Interaxle Differential Lock Telltales
These telltales will light up yellow when
the pneumatic switches for either the wheel
or interaxle differential lock are turned on.
For the interaxle lock, the telltale is acti-
vated by the switch. For the wheel lock, a
switch in the axle turns the telltale light on
only when the lock is actually engaged. It
turns the light off only when the lock is ac-
tually disengaged. See page 258 for proper
differential lock use.
