LED Fusing Considerations
Although the average current draw per module is very low, due to the type of circuit used to power each module, the instantaneous
peak current to a module can be significantly higher during low voltage conditions. To avoid prematurely blowing ATO style fuses
or tripping breakers it is recommended the following rule-of-thumb be used to size fuses or breakers. This is especially important in
lightbars with many LED modules running off a single fused source.
Minimum fuse size calculation: (See Wiring Diagram page 5)
For LED 12 volt electrical current
1.5 X (number of 6LED modules being fused) + .5 X (number of 3LED modules being fused) = Total Electrical Current at 12.8 VDC

WARNING!
Flash Pattern Changes
LED Lighthead Flash Pattern
Place the unit on a clean work surface and remove the outer cover. With the chassis facing up, locate each lighthead mod-
ule circuit board.
To change the flash patterns of the LED Lightheads, touch both posts of the J1 header simultaneously
with an electrically conductive tool such as a screw driver blade (see Figure 13 below). Repeating this proceedure allows
the operator to cycle through the numerous flash patterns offered until the desired pattern is achieved.
