Drivers may install on their private vehicle:

A muffler cutout, bypass, or similar device.
A blue light visible outside of the vehicle.
A siren.
None of the above.
Explanation

According to Hawaii law, certain equipment, including sirens, muffler cutouts, and blue lights visible outside of the vehicle, are prohibited on private vehicles. Sirens and muffler cutouts are only allowed on authorized emergency vehicles, while blue lights visible outside of the vehicle are restricted to such authorized vehicles as well. Therefore, drivers are not permitted to install these devices on their private vehicles under Hawaii law.
