-10-
You may skip this section if any of the following is true:
• Your lightbar is not equipped with a Traffic Director control circuit
or
• Your lightbar came with a TD77-2 Traffic Director Control Box and you will be
using it
or
• Your lightbar came with the Traffic Director control circuit but it did not come
with a controller and you will be using the internal controller with standard On/
Off switches that switch +12VDC
The Laser Traffic Director circuit has two internal jumpers that will allow it to be operated
through the internal controller via standard +12VDC On/Off switches, or to be operated
with an external ground-side switched Traffic Director controller of some sort (e.g. Star
model TD77-2).

the internal controller with positive-side switching.
These default settings are shown to the left.

If you will be using an external Traffic Director
controller that is ground-side switched, such as our
TD77-2, set your jumpers as pictured to the right. If you
ordered a TD77-2 with your Laser lightbar, the jumpers
should already be preset for use with the TD77-2.
DO NOT use either of the configurations pictured below!! Your traffic
director WILL NOT function properly.
