I have a Whelen Advantage model 4400-HID with Arrowstick. I do not have the arrow controller. All lights rotate as they should. 2 of the 4 DO NOT light up. Unsure if it is the Ballast, or the bulbs. Lenses are Red with Clear center (Diamond Mirror in center) to the from and Red with AMber center to the rear. The end caps have alley light cutouts, and there are alley lights in the bar; unsure on operating condition. Also, Screw hols on the upper holes of the encap are cracked. Asking $175 OBO plus shipping. PM with any questions.
