Question

Who has noticed the many cars with only one brake light, even on new cars. What is behind this?

Answer 1

now that everything is being made in china, we get nothing but c**p.

Answer 2

I see 20 plus cars and trucks a day with this and I believe that is it caused by the use of cheaper quality bulbs.

Answer 3

people can't see if their brake lights are working or not, and many don't think to check them, so they don't know when to replace them. whereas if a tire goes flat, or a headlight blows, you notice the fault easily and fix it.

lights blow all the time because incandescent (lights with a filament) are very sensitive to bumps and vibrations. the filament in them breaks very easily when hot. not the best option for a car which hits 1000's of bumps a day, but one of the only ones up until LED's became more available.
