you might want to find out what you can and cant have on your car.every place is diff read up on local ans state law to see what a vfd can have. im my area vfd can only have a blue light no red or sirens and the blue light must be on the roof. cant have it inside or in the grill and no head lights or side markers flash or strobe.and if you just joined i would wait a few months after . our local wants you there 6 months with all your training done be for you get a light.and the blue light just means nothing as well its curtisy you cant speed people do not have to move and you cant run lights or stop signs. so make your thoughts out well be for you spend $100 and up on a light
