Q & A


  1. What are Lightbars, sirens&speakers?

    1. Emergency vehicle lighting is visual warning lights fitted to a vehicle for use when the driver wishes to convey to

    other road users the urgency of their journey, to provide additional warning of a hazard when stationary, or in the

    case of law enforcement as a means of signaling another driver to stop for interaction with an officer.

    2. An electronic amplifier & siren, or (informally) amp is an electronic device that increases the power of a signal.

    It does this by taking energy from a power supply and controlling the output to match the input signal shape but

    with a larger amplitude. In this sense, an amplifier modulates the output of the power supply to make the output

    signal stronger than the input signal.

    3. A siren speaker is a loud noise-making device. Civil defense siren speakers are mounted in fixed locations and used to warn of natural disasters or attacks. Car speakers are used on emergency service vehicles such as ambulances, police cars and fire trucks.
