Siren Switch Honker is now integrated into Siren Mastery. You can replace the switch sirens sound files with the ones included in Siren Switch Honker's download. British UIs will also soon become available!
 
Siren Switch Honker
Siren Switch Honker is a script modification that allows you to simulate a honking sound whenever you toggle your siren tone. It supports non-default siren toggle keys and controllers, as well as variable toggling sounds.
Having the horn sound for a short moment when toggling sirens is common in British police cars.
Thank you @Double Doppler for the default sound files.

If all else fails: Please leave a comment (not a review). Include your RAGEPluginHook.log file, located in your Grand Theft Auto V folder. Also, please provide an accurate description of what happened. This allows me to help you as fast as possible.  
Somebody rightfully pointed out to me that the ELS/USA siren switch tones can also be simulated using this modification. You can get it here:
