For those who don't know I also run a youtube channel, Today I posted a Short video on the history of the streethawk lightbar which was used by housing in the 80s and 90s and then PD in the 90s and 2000s. If you like it subscribe because I can promise you there will be more NYC spec posted on there
Just some cool reference photos, Southern Pacific Railroad Police from the 90s, courtesy of AJ Illenota on the "A fire truck (or emergency vehicle) of a different color" Facebook page.
