New LED tail lights 69 Cuda

Have you actually READ this thread? Apparently, you're just ignoring what you don't want to hear.

For the purpose of certification and legality, neither your subjective opinion nor mine are relevant.

ONE MORE TIME, certification is not a simple measurement of brightness. It's light measured at numerous angles and conditions using special equipment, not determined by some guy in a lab coat with a clipboard just watching it flash. Just because you don't understand why it's so important doesn't mean that it isn't important.

If you and I are standing on the street and a car drives by, I might guess the car was traveling 30 mph, and you might guess 80 mph. Neither estimate matters, only a mechanical speed detector could make the correct determination. Otherwise, why would cops use speed guns? They could just "guesstimate" who's speeding and who's not.

That's exactly what it's like living in several less-developed countries. Laws like this are what separates us from them, and I'm THANKFUL for these laws, even when they "inconvenience" me or my hobby.

Who the hell said it wasn't important. What I find important is actually knowing what I'm talking about. I think it's funny how a lot of you just keep using the words "certification" and "regulations" like you actually know what your talking about. You just keep parroting what Slantsixdan mentioned in earlier posts even though he doesn't actually mention what the specific laws are. He mentions FMVSS 108 which is a 60+ page document about the standards of "replacement lamps, reflective devices, and associated equipment," multiple times but never actually points out specifically which standards relate to LED taillights. Then you completely ignore the information Sebastian gave which explains how the entire process of certification works. Read the part under Certifying Lighting Equipment.

Here's the link he gave:

I may not be able to "guestimate" if a car is going 30 or 40 mph but I can damn well tell you that its not standing still.
