Whenever I see this collection, I wish I was somewhere other than in California. Quite a few of these lights were never used on EVs here, like the Beacon Ray 15 series, because every light (and siren) used on an EV, or actually any warning light used on a vehicle that uses public streets, must be type approved by the CHP. I understand that approval is time consuming, and fairly expensive. I was told some years back that the cost was at least $50,000., so some manufacturers just skip it, unless they think they can sell a lot here, like Federal, Whelen, and Public Safety. Someday, this fine and growing collection should be in a fire museum.
