Some parts of the U.S. still works under a volunteer system. Sometimes those volunteers are 10-20 miles away depending on the size of the catchment area. Lack of call volume, and tax support, in these areas necessitates volunteer responses. This is not to invoke a discussion about volunteers, but volunteers are a vital part of EMS today, and lights on their cars are part of their tools of the trade. Until the pendulum swings to paid services nationwide, we should support our peers and their different issues. To not understand that side of our profession, and why they are there today, is to not totally understand our profession. My understanding of the original poster was that he wanted help in choosing lights for his vehicle that would allow him to do his job safely. It is unfortunate that he was looked down upon and thought less of because of it.
Just another quick note... if a volunteer spends a few hundred dollars on equipment to keep his EMS unit going, it is probably a lot less, by thousands, than what his taxes would be raised per year if they did not have him and had to put a full time unit up. Not a bad investment.
