Progressive vs. Independent Switching
In a 3-level progressive switch application there are only 3 patterns that typically need to be set.
Example 1: Using the defaults in Table 2, the patterns displayed would be as follows as the switch is moved from the off position
through Levels 1, 2 and 3:
Level/Switch Energized
Wire Color
Pattern Description Notes
1 Blue 13 Fast In-Out Quad REAR Only Level 1 is energized.
2 Blue + Orange 1 Fast In-Out Quad FRONT/
REAR
Level 1 is still energized, therefore
the pattern displayed is dened by
the "Blue + Orange" default. In this
instance the ash pattern chosen for
the "Orange" wire by itself (pattern 25)
does not come into play because the
switch is progressive.
3 Blue + Orange
+ Yellow
11 Cycle FRONT/REAR Levels 1 & 2 are still energized, there-
fore the pattern displayed is dened by
the "Blue + Orange + Yellow" default.
In this instance, the ash patterns
chosen for the "Blue", "Orange" and
"Yellow" wires by themselves do not
come into play because the switch is
progressive.
In an application with 2- or 3- independent switches there are "combinations" of wire colors that can have unique ash patterns
dened, thus allowing the switches to simulate a progressive style application. It is intuitive to think that only two unique ash patterns
can be displayed in a system with 2 independent switches; however, a third pattern is available. In the below scenario 2 independent
switch can mimic a 3-level progressive switch.
Note: Remember that switches that are not progressive operate completely independent of each other.
Example 2: Setting Blue to Pattern 13 (which is the default), Orange to Pattern 1 (which is NOT the default), and Blue + Orange to
Pattern 11 (which is NOT the default), the patterns displayed would be as follows for a 2 independent switch application:
Level/Switch On/Off Wire Color Pattern Description Notes
1 ON Blue 13 Fast In-Out Quad REAR Only Level 1 is energized.
2 Off Orange
1 Off Blue
2 ON Orange 1 Fast In-Out Quad FRONT/
REAR
Only Level 2 is energized. If the ash
pattern for "Orange" had been left at
it's default factory setting (pattern 25),
then the light bar would have ashed
in a "Fast In-Out Quad FRONT" only.
1 ON Blue
11 Cycle FRONT/REAR
Both Levels 1 & 2 are energized,
therefore the pattern displayed is de-
ned by the "Blue + Orange" pattern
that had been set by the user, which
was Pattern 11
2 ON Orange
Note: in the above scenarios the Blue and Orange wires are not being tied together in nal installation, however, they do need to be
tied together when setting the ash pattern for that combination of wire colors. The "Blue + Orange" description simply identies that
a unique pattern can be chosen for the scenario where both Level 1 and Level 2 are energized. In order to achieve proper operation
of the lightbar all possible combinations of the independent switches must be programmed to the desired pattern.
