Runway guidance signs lit with halogen or fluorescent lights are not as effective as LED ones. This is because the energy consumption for older illuminated models is high, in addition to maintenance and spare parts costs.
This is why LED retrofit kits offer a solution to replace older models with LED technology, which is more efficient in terms of consumption and uniformity of track guidance signs. The installation of these kits in traffic signs, without any change in structure or components, is the best solution to renew the signs instead of buying new signs.
