In this time, I will show you car bulb test in brief.

All of our car bulbs will be tested at least 3-5 times.

When raw materials of our car bulbs coming, we need to test them at the first time.

Then we making some sample car bulb to test if all materials are good.

After finishing car bulb testing, we start to produce them.

During producing time, every car bulb will be tested one by one again.

Before packing car bulbs, all of them will be tested again.

So you don’t worry about our quality because all of our car bulb test very carefully.
