Car lamps, also known as headlights, may require brackets for several reasons:

1. Proper Alignment: Brackets help ensure that the lamps are properly aligned. Proper alignment is crucial for the effective functioning of the lights and for maintaining road safety. Incorrectly aligned headlights can cause glare for oncoming drivers or reduce visibility for the driver.
2. Secure Mounting: Brackets provide a secure mounting point for the lamps. This is important to prevent the lamps from shaking or vibrating while the vehicle is in motion, which could affect the stability and effectiveness of the lights.
3. Adjustability: Some brackets allow for the adjustment of the lamp angle. This feature is useful for fine-tuning the direction of the light beams to achieve optimal visibility on the road without causing discomfort to other drivers.
4. Protection: Brackets can help protect the lamps from damage. They act as a buffer between the lamp and potential impacts, such as small collisions or debris on the road, reducing the risk of damage to the lamps.
5. Regulatory Compliance: In some regions, there are regulations and standards regarding the proper installation and alignment of vehicle headlights. Using brackets that meet these standards ensures compliance with safety regulations and contributes to road safety.
