The Tornado X goes above and beyond other Siren-And-Beacon products.
With the ever-impressive Tornado V2.0 mounted atop you're guaranteed to be seen, and although the siren output is only 20W, it is still able to achieve sounds up to 115dB!
The beacon also conforms to ECE R65 Class II and offers 9 flash patterns, included simulated rotating. Also the magnetic version comes with a free carry case and 146mph magnetic rating to boot!
For a neat, unobtrusive and convenient solve-all solution, there's no need to look further than the Tornado X.
