Here is a scientific test you can perform at home.
Buy one head light bulb made in Mexico and one made in Germany,
put one on the left side of the car and one on the right
and see which one lasts longer.
I did the test the one made in Germany lasted 9 years.
The one made in Mexico lasted 3 months.
They both cost the same.
My motorcycle head light bulb made in Mexico lasted one hour.
