The yellow lamps in the light bar may emit several different patterns to the rear.
Sequentially Lefto Right, Righto Left, starting in the middle and diverging out.
All flashing On and Off, maybe others.
Since themergencyehicle does not stop on a road or athe side of a road, none of these patterns are needed. Though the light bar controller has buttons for different patterns, I would never operate any.
The twoutmost amber lamps are now connected as turn signals. (They match the vehicle’s yellow tail turn signals.)
After midnight last night, coming upon a herd of deer on a mountaihighway, I turned on the four-way-flashers. The amber lights worked well at warning the semi rigs following well behind.
When emergency transports (red, white, blue lamps flashing) the amber turn signals arespecially useful for changing lanes or entering or exiting Interstate highways.
They are legal, but I wanto find a way to electronically dim them at night so notoo bright
in theyes of driverstopping behind.
