I tried ordering through there. Waited a month and never received my order and or a response to any of my emails. Had to dispute the transaction and he didn’t respond to eBay or PayPal either.
A lot of the Denver metro area agencies still have that setup (but with newer LED bars). The City of Denver runs those with Whelen Freedom bars. They have a California steady red thing going on their highway rigs.
He said he only responds to the station, so I doubt rear lighting would really do anything for him. I also only respond to the station and have only front lighting.
Don't know a thing about it but it looks like it's darn nice for the age and the price seems decent at $200
