I was experimenting with two versions of this truck one that uses paints liveries to rotates message board and another that uses vehicle extra components.
using liveries you can have over 30 messages combinations to choose from and can customize messages in the ytd.
However this eliminated the ability to have a multi livery paintjob.
pattern is set by non els sequencers set to three sirens, so each message is a three part message.
SIREN 18: SLOW DOWN
SIREN 19: MOVE OVE
SIREN 20: ACCIDENT AHEAD

atm the flashes due to non els pattern
was thinking about adding a steady burn option via the extra vehicle component’s
Message sign trailer and truck mounted message board options
working on three versions
steamable version, that can stream anything to the LCD
and other options
