Flash Pattern Selection:
The light head flash pattern may be changed by touching the Blue wire to ground for the following intervals (while the light head is flashing):
- A quick tap will increment by one pattern.
- Hold until the unit lights, then turns off to go to the previous pattern.
- Hold until the unit lights, then turns off, then lights again to reset to the factory default pattern.
- Hold until the unit lights, turns off, lights, then turns off again, then goes off again to set to steady burn.
Wiring Instructions:
Wire as shown in FIGURE 2. All wiring should be a minimum of 18 AWG. The
positive line must have a slow blow 5 amp fuse. Routing the ground wire directly
back to negative battery terminal is recommended. Pack dielectric grease, such
as Dow Corning 4, around each electric connection exposed to moisture or the
ambient environment. Isolate any unused wires.
Caution!
When drilling into any vehicle surface,
make sure that the area is free from any electrical wires,
fuel lines, vehicle upholstery, etc. that could be damaged.
Mounting Instructions:
Important!
This unit is a safety device, and it must be
connected to its own separate, fused power point to as-
sure its continued operation should any other electrical
accessory fail.
Select a flat mounting surface with optimal visibility to oncoming traffic. Using the
product as a template, drill two holes matching the holes in the unit. Secure unit in
place as shown.

Synchronization:
The directional is capable of syncing with other compatible ECCO products by following the steps below:
1. Set the desired flash pattern on each unit individually. It is also strongly recommended that the same rate and style of flash pattern be used on all synced units to
produce the most effective warning pattern.
NOTE: To operate simultaneously, each unit must be set to the same phase (A + A or B + B); to operate alternately, units must be set to have the opposite phase
(A+ B or B + A).
2. Connect the yellow sync wires together and check that the units are flashing in a synchronized manner as expected. If a pattern on one unit appears incorrect, the
blue pattern select wire can be used to cycle forward or backward on that individual unit until the correct pattern is selected.
NOTE: This will only change the pattern in the one unit and will not affect the other units connected to the yellow sync wire.
