Well, I'm in the U.S. and the first American maker to put DRL on their cars
used brights. I read articles on it. I see them. The inside lights of the
separate high/low are highs. These are the DRLs.

The idea behind using high beams is to make sure that other vehicles can see
the car. Low beams are designed not to be seen by other drivers. The high
beams at 60 or 80 percent brightness are much more viasble.
GM isn't wrong because they didn't do it the way you expected; they are just
different.
