I recon that case have it screwed up..
During the day time the 3/4 full stay on, sot he chaser driver thinks your full.
At night 3/4 bin flashes several times then off which is good because its very annoying for the driver and others in the field to have flashing light on all the time, thats 1 plus for Case
new holland machines running accross the rd, at night , 3/4 bin flashes few times then off for say 30sec then flash a few times and so on until full, i presume they flash more or full on when full.
Im sure that an update would allow for some user preference setup, cant wait to see that
