No doubt! Amber frontal lamps are compulsory for trucks to be considered safe to drive.  Most people probably don't give much thought to these bulbs and might not even know why they're mandatory. The authorities demand the installation of these lamps to increase the visibility of heavy-duty vehicles to other drivers on the road. The required placement for these bulbs is 6 to 12 inches above the ground, usually roof-mounted on large vehicles. The purpose is to increase the vehicle's visibility and provide a visual cue for other cars and motorbikes regarding how far away they are. These lights are both a safety element for the people inside and an alerting signal to other vehicles.
