161 decibel freight train horn attached to black CAP-IT tool box. This was installed in my 2016 f-150. This horn is the same horn used on fright trains to warn on coming people and traffic near rail road tracks. This thing is LOUD, and AWESOME! Paid $2500 for the horn and all the parts, $400 for the tool box. Currently the pump needs to be replaced $350 from CAP-IT. Will sell the tool box and horn and all accessories for $650 Box is sitting upside down shown in pictured, when installed the horns sit under the tool box
