As you know, most of our automotive lights will be tested at least 3-5 times.

When materials of automotive lights arriving at our factory, we need to test them one by one.

Then our technicians make some samples of automotive light to test life time, lumens, watts, volts and so on.

If all data of tested automotive lights are good, we will start to produce them.

During producing, all of half automotive lights will be tested again by machines.

After installation, all finished automotive lights tested one by one again.

Due to very serious automotive light test, it helps my factory win a good reputation.

I will attach pictures of Automotive test light as below and you can check it.
