The BST warning light is available in different signal colours, dimensions and mounting variants. 3 or 6 power LEDs in the colours yellow, blue, red or white ensure an optimal signalling effect. The light can be synchronised with two or more units and has different flash sequences. In addition to the continuous light function, four different flash patterns can be set and are approved according to the European directive for beacons ECE-R65. The warning signal (single to quadruple flash) is either synchronous or alternating. Variants with "1 level" produce a constant level of brightness independent of the ambient light. Variants with "day/night mode", adjust the brightness to the ambient light. This ensures increased visibility during the day and the avoidance of glare at night. The housing is attached to the vehicle by means of screws for fixed mounting and by means of a bracket for bracket mounting. The warning system is also available as a slim version with a mounting height of only 12.8 mm. It is particularly suitable as an attention-grabbing warning signal and for safeguarding danger spots. The product can be mounted horizontally or vertically in various positions around the vehicle, depending on the variant.
