This is where using a vehicle as a firefighter is different than as LEO. A patrol vehicle is a tactical tool for us as much as it is a way for us to get from point A to point B.
How about proper intersection and side lighting? My agency runs a lightbar as standard issue only.
Headlight flashers on an Impala (and HAWS in headlight housing) are pointless in the Impala. Our Deputies are often left to block off lanes of traffic by themselves. One light bar from the side is not nearly effective. Is it visible? Yes... is it safe no.
I have added several lights to my vehicle that have GREATLY enhanced my safety. Both while dealing with traffic and while dealing outside of traffic. I have enough scene lights at multiple angles that I can effectively park my car facing a house, exit my car, circle the residence, and come up from behind the people walking out of their front door without them ever seeing me. It has given me a tactical advantage on numerous occasions.
A lightbar alone would not do that. A lightbar alone does not give enough driving light to avoid certain hazards in some of the areas we patrol. The total minimum amount of time I drive "code" each shift is 2.5 hours. I can assure you I am MUCH safer with strategically placed lighting. That being said, I would want quality lights, however; if my budget is $4,000 I wouldn't be as safe with just a $4,000 lightbar.
The legacy is a beautiful bar... and if i had the money, I can't say I wouldn't like to have one. But I don't
