Headlamp tester

A headlamp tester is a special machine that checks how well the lights on your car work at night. It's like a little robot that looks at your headlights and makes sure they are bright enough to see the road when it's dark outside.

When you drive at night, it's important that your headlights are working properly so you can see where you're going and avoid any accidents. The headlamp tester helps you make sure that your lights are working correctly and they won't blind other drivers on the road.

First, you drive your car onto a special platform where the headlamp tester is located. Then, the tester will shine a bright light towards your car's headlights to see how much light they are producing.

The machine will then check to make sure your headlights are pointed in the right direction so they don't blind other drivers or shine off into the trees instead of on the road.

Once the headlamp tester is done with its inspection, it will give you a report that tells you if your lights are working properly or if they need to be adjusted or fixed. This way, you can stay safe on the road and avoid any problems that might come up if your headlights aren't working properly at night.
