Holley Retrobright Price Match

If you drive your car at night at all, you're wise to steer clear, no matter what price you might find them at. There are legitimate (effective, safe, legal) LED headlamps to fit any sealed-beam car, but the RetroBrights are not on that list.
Is this still the case

Yes.

or did they change something?

No.

Looking at their website at least they seem to be pretty up front about it and say they are made by Morimoto

Morimoto is not a company, it is a brand belonging to TheRetrofitSource, a longtime US-based seller of (almost nothing but) unsafe/illegal lighting trinkets. They farm their production out to various job shops in China.

and meet DOT requirements.

Nope. This is an out-and-out lie.

I know plenty of knock off places claim DOT compliance as well, but I give Holley at least a tiny bit more confidence

Why? You shouldn't. The only thing they have to do with this product is their name on the box.

That doesn't mean that DOT regulations make a good headlight

Correct—there are lousy DOT-certified headlamps, and there are very good ones, and a lot in between. And there are very good non-DOT-certified headlamps, too. None of that applies to the Retrobright things, which are fraudulently DOT-certified, lousy headlite-shaped trinkets.

in many regards though, just a "legal" one

This is a lot more than just a divergence from some picky little requirement in a lawbook.
