If you're looking to add a scale, working police light bar to your R.C. Vehicle, you've found it! This light bar is sized for 1/18 & 1/10 scale vehicles and is controlled by a main power switch, and two small momentary switches. One momentary switch controls the light pattern on the front and the other switch controls the rear traffic advisor. This light bar would look great on the top of any R.C. Police car project, or that 1/18 scale diecast you've been wanting to add a light bar to.
