- Federal Signal
Had plans to use this in my truck but went with an interior lightbar. I used this temporarily as a dash light until I got my install done. I can leave the 4 feet of whelen cig plug switch on there or cut it. Buyer choice. Comes with original bracket and choice of headliner bracket. Please note I have another viper S2 for sale and it will be first come first serve on headliner bracket choice. Second buyer will get which ever is left over and I will update which one is left when the other sells.
