Suction cup-type headlamp aiming equipment is suitable for projection type headlamps and assemblies with internal adjustments, ensuring correct light direction and safety.
Step-by-step explanation:
Suction cup-type headlamp aiming equipment may be used on different types of headlamps, including projection type headlamps or headlamps with internal adjustments. The equipment is designed to help align the headlamps properly, ensuring that the light is directed correctly onto the road. This ensures the safety of the driver and others on the road by providing adequate visibility while reducing glare for other drivers. It is important that headlamps are aligned according to the manufacturer's specifications to achieve the best performance. For HID type headlamps and those with protruding pegs, the equipment may not be compatible due to the specific design and assembly of these headlamps.
