لوحة حدّ السرعة (SLS)

Speed limit signs define the permitted speeds for vehicles on public roads and are one of the primary measures available for controlling traffic speed. They are typically mounted in school areas, on lanes, highways and in tunnels.

Alliance builds its signs on Surface-Mount Device LEDs with optical lens engineering, which outperform traditional DIP LED designs on reliability, power draw and legibility in bright sunlight and adverse weather.
