We have been building up vehicles with two-tone sirens for over two decades, including for police. All changes over the years have been followed and supported by us. We can therefore give you excellent advice. When installing a two-tone siren, we take into account your wishes and requirements, but also the most sustainable power consumption possible. We build your vehicle up with the signaling, controls, tools or installations to your liking. We are always able to realize a suitable solution.
