The requirements of the ICAO (International Civil Aviation Organization) prescribe that aviation obstructions be clearly marked with corresponding certified obstruction lights.

The obstruction lights Skyline Alpha correspond to these requirements according to ICAO Annex 14, Chapter 6, Table 6-3.

Skyline Alpha is designed on the basis of LED, thus enabling almost maintenance-free operation, and achieves an extremely long lifetime.

Four different models are available for the various mounting situations and are naturally available in the commonly available voltages 24 VDC and 115/230 VAC.
