Warning lights are important safety instruments in road traffic and on construction sites. They are used to make dangerous areas, obstacles or temporary traffic routing clearly visible. With their eye-catching, usually flashing or rotating light signals, they warn road users of potential dangers in good time and guide them safely around them. Warning lights are available in various designs, including battery-operated models and those with integrated solar cells. Their robust construction and high luminosity make them indispensable tools for traffic safety, especially in poor visibility or in the dark.
