That stamp is actually worthless.
APC had a bunch of their clear taillights hauled in front of the DOT 10 years ago and declared illegal because there were no red light bulbs that met the spectral requirements for "red" as defined in title 49CFR 571-108.
SAE/DOT on the lens simply means that the manufacturer CLAIMS that the assembly meets requirements. There is no regulation on the manufacturer side.
