Amber Signal

By warning signal we mean amber light signal. There are no other colours in this category (pure white, green, purple). The warning signal does not include an acoustic signal, it consists only of a light signal. Vehicles flashing yellow should be approached, passed or overtaken with extreme caution.


In our amber signaling light product portfolio you can find SoundOff Signal, Code3, Premier Hazard, Sirena and Strobos brands. The amber flashers are available in the form of lightbars of different sizes. Yellow perimeter lights are typically mounted on a grille, door, rearview mirror or behind a windshield. Amber mobile lights are available with either a fixed, drill-in mounting or a magnetic base. Previous technologies, halogen and xenon bulbs have now been replaced almost without exception by LED technology which guarantees extremely reliable, long life and low consumption. Our products comply with R65 lighting parameters and R10 EMC compliance. You will find additional, extra services for almost all of our products, such as installation of devices in a vehicle, service or maintenance.

Use of yellow flashing lights

The IRM Regulation 12/2007 (13.III) distinguishes 2 user groups for yellow flashers. The first group is those who are entitled by virtue of the Regulation to use a warning sign, and the second group is those who are required to obtain a special authorisation from the authorities.


The authority has the right to revoke the authorisation to use the amber light if there is a change in the circumstances entitling the vehicle, in the facts giving rise to the entitlement or in the identity of the operator. If the holder does not use the amber light in accordance with the law, the police station will require the holder to dismantle the device.

Components of the warning

  • Lightbar: Halogen or LED technology, fixed or magnetically mounted.
  • Beacon: Typically a yellow roof light, either fixed or cigarette lighter operated.
  • Perimeter lighting: Depending on the size of the vehicle, an additional amber light may be required for visibility of the warning signal, mounted in the engine cooling grille or door.
  • Siren: A simple switch, less frequently a control, for switching amber lamps on and off, which is used, for example, to change the frequency and direction of the amber light flashing.


In the case of the installation of amber lamps, it must be ensured that the direction indicators are adequately visible from all sides of the vehicle and that a light bridge or roof-mounted indicator is fitted at the highest point of the vehicle.
