NFPA Freedom

[theroofable]

Our engine has a 72 inch freedom with corners, 2 red and two white led heads to the front. The mfg date is 11/05. It is time to add some more modules to this bar, are these prewired internally or will it be complicated to add two pairs of lights to this bar? Either way it will be done. Also, are these ballast or passive bars? The model number is FN72QLED. I have never messed with an NFPA bar before, help would be appreciated.

The wires should be there. Can't tell you on the rest of the questions.

The install guide doesn't specify the type of flasher used in the bar but there should be wiring in there. If not you might have to add a harness to the existing flasher. You'll have to connect the appropriate trigger wire to the switchbox as well. Last resort would be adding an additonal flasher but that wouldn't be tough at all.





Freedoms are passive.

LEAVE IT AS IT IS! IMO, You dont need more LEDs. Those bars are very effective as is.

Less is more. If you really must add lights, synchronize them - Freedoms with with more than a few sets of lights are very prone to turning into a glowing blob, which really defeats the purpose of flashing lights. With just the minimum number of lights in an extra-long bar like you have, you get a lot more warning out of each light.

I agree. However we are adding blue to it and I cannot turn the red lights into blue lights, thus requiring me to buy more lights, and rather than do away with them, Id rather keep the heads in the bar. How would you go about syncing the lights?

I found what I believe to be a SX-series Liberty control board, from the factory, installed in a 2012-dated 66" NFPA Freedom that was ordered fully loaded with 8 modules to the front, four corner modules, and one module in each of the endcaps. Perhaps it was built this way because it had so many modules in it; I cannot say.

If you really must add lights, synchronize them.

Your Freedom may be different than the one I worked on, but this worked for me: http://elightbars.org/forums/f32/sync-option-whelen-liberty-sx-model-lightbars-19101/
