emergency lights

I see on here that there are a lot of people who are volunteer firefighters. My question is, I have the front and back of my 2002 ECSB truck lit up but the sides are lacking any significant warning power. Currently I have Strobes in the highs, DRLs, and tails, 4 TIR3s in the grill (2 red, 2 white), 2 TIR 3s in back and a red SHO-ME LED mini on top. I really need some suggestions as to something for the sides and the cheaper the better as always. I have a few alt. flashers on hand. Also if you know of any cheap LED lights that would be great. Thanks, Derek

PS I also run a 200W siren (whelen box, 2 dynamax speakers)

One more thing, if anyone has video of their truck with the lights on I would love to see it. The guys on my department are a little competitive so I need any advantage I can get. Thanks, Derek
