Amber Perimeter Light

Depending on the size of the vehicle, the use of an additional yellow light may be necessary to increase the visibility of the warning signal. The amber perimeter light must provide a strong light effect to warn road users of the danger and protect workers even in extreme weather and visibility conditions.

When should a yellow perimeter light be used?

An amber perimeter light signal is not a substitute for a primary lightbar or mobile light, but a complement to it. The Hungarian standard stipulates that the amber perimeter light must only be used in conjunction with the primary signal, taking into account the installation specifications and the rules for its operation. The yellow flashing light is intended to increase the visibility of vehicles using the warning signal.


In most cases, only modern LED designs are available, but in the past, halogen and flash tube designs were also available. In general, amber perimeter lights are fixed, with the exception of the windscreen flasher, which can be suction-cup or self-adhesive or Velcro. Manufacturers use different design parabolic mirrors, possibly with headlamp magnifying lenses, to increase the light output.


Depending on the vehicle type and product type, the amber auxiliary light can be used for 12-24V VDC systems. In the area of compliance with standards, photometric compliance parameters R65 and electromagnetic compliance parameters R10 shall be met.

Positioning and control of the amber perimeter light-signalling device

Most amber auxiliary light signals can be installed almost anywhere to suit the user's requirements, subject to compliance with the regulations. It can be mounted on the front bumper or in the grille, on the rear-view mirror, on a side bodywork element or even behind the front windscreen or rear window, or even on the rear door or door frame. When installing a yellow roof lamp, it should be taken into account that the lamp must provide 360° visibility overall, but that this cannot be provided by one device due to the design of the bodywork, an additional yellow lamp or an additional yellow lamp must be installed.


The amber signal is controlled by a push-button switch with an optionally selectable flashing pattern. It provides synchronisation possibilities when more than two lamps are controlled together. The flashing pattern of the amber light is a set of pre-programmed timings, which can be selected by the installer or the user according to the requirements of the country.

Who can use amber flashing?

The use of amber flashers is regulated by IRM Regulation 12/2007 (13.III), which distinguishes between two groups of users, those who do not need an official authorisation to install them and those who may be granted an official authorisation if the purpose of the vehicle operation justifies it.
