This box is off a '95 GMC 2500 pickup truck. The work lights worked when we took it off, but the beacon lights did not. I'd assume it was a wiring issue or a broken switch in the truck. All the side doors open and close fine. This box is located in Mazomanie, WI. Will not ship, will not deliver. Pickup only and I can help load it on a trailer or mount it on your bed. $500.00 obo. send me a PM.
