Vehicle Lighting & Installation

We are the Largest Local Distributor in WI of All of Our Light Lines!

Kaestner is the largest local distributor of emergency lighting to the construction, municipalities, and trucking industry. We keep a large in-house supply of light bars, strobes, camera systems, backup alarms, and much more. We also install these systems in our service department. Kaestner’s is now selling amber/green strobes in Whelen, North American, and Triton lighting lines.


2021 Wisconsin Act 225 now allows county and municipal vehicles to use green strobe lights. We have plenty in stock for your vehicle or vehicle fleet!
