Just wonder if someone has any knowledge about a Whelen Legacy I have acquired. It's on a 54 inch frame but no I/0 board just a ULF44 flasher. It has no real inboard modules just dummies and same for TD and ally modules. All brackets and optics are there just no LED boards. The only real modules in the bar is the corners. Only function is steady burn, and has a battery pack inside the bar and charging plug on the bottom with a off on switch. Just curious what this may have been used for or if this is even factory Whelen.
