Has any one modified this for a visual indication or a louder audible indication? I'm not a wealthy farmer that has cab'd tractors with A/C and all and it is all I can do to hear the accu-bale alert over the tractor and I wanted to wear hearing protection. If I were to wear hearing protect I would never here the alert. I actually changed tractors to pull the baler this weekend cause I couldn't hear the alert on the larger tractor.
