I already have the 2 dash lights, i'm only getting 3 more lights. Our company allows us to have lights as long as their blue only. No strobes, no headlight flashers, no sirens. The rear deck light would be for when my vehicle is on the side of the road because there are times when i go direct instead of taking the engine because i'm too far out and can't make it on any of the trucks out. And the grille lights would be because sometimes because my truck is higher up off the ground people don't always see the dash lights that well, unless i get right up on them. I feel that maybe if the lights were lower, like somewhere in the grille, that smaller cars would see them better. I just want something small for the console, not a whole bunch of switches and crap. I was thinking maybe just a 5 or 6 function switch panel, but i need something to mount it in. Unless i could do it some other way, like i said i don't wanna ruin my truck or have wires running everywhere. I already have 2 wires running from the 2 on the dash. Rick-James, don't worry, no offense taken. Yea it's volunteer. We live out in the boonies here, so a lot of guys are pretty far from the firehouse. The lights at least help a little trying to make calls on time.
