Updating the lighting on our donated engine. its a 82 Pierce. Has the old silver square box opticom strobe on the roof. Inside the cab has 2 switches for it, theres 3 style patterns. Question is this. Im putting a new lightbar on and since we dont use the opticom (we dont have the system in our city) its probally going to come off. What are these worth? I know someone out there with a 70s-80s truck would want this.
