Whelen demo 

Howdy...as a warning lites "observer since 1954,l.e.d.z. So radical from the beacon-ray &unity steady-burn flashers of 1959s....those amazing,sick rotobeam ltbars just too cool 👍🤯

I'd like to get my hands on those demo units.

What is the model designation of the 180-degree LED rotator?

Those lights are so bright they should be illegal. High beams when others are around are illegal. Why aren’t these?
