For the record:
DOT and SAE DO NOT APPROVE anything, there is no such thing as DOT APPROVED or SAE APPROVED.
The MANUFACTURER is the one who SAYS his product MEETS the requirements of DOT or SAE, and, for many lighting companies, ALL that might mean is that they figured out how to make letters appear on a product, such as D's, O's and T's, etc....
Or, maybe, it can mean that DOT requires a light to fit into a particular housing...and theirs fits, so it MEETS that particular DOT specification, but, doesn't mean it meets ANY OTHER DOT specifications, such as the beam distribution pattern, etc.
So, DOT and SAE , do NOT approve PRODUCTS, ever. They issue standards, and, manufacturers can say they MET the standards, but, legally, they CANNOT say that DOT, etc, APPROVED the
products.

Some reseller OF the products don't know this, or, don't care, etc...and advertise that a product is "Dot Approved" or "SAE Approved", etc....but, the product is not, ever.
Its more accurate to say it MEETS a particular specification...but, you then have to read that spec to know what PART of the light this applies to.
Saying it is compliant, rather than approved, would also be legal, if it WERE actually in compliance.
