Modern style headlights
Didn't read through the entire thread because I know these threads normally spiral into a technical nightmare.
But I personally bought a set of the crystal diamond lights with H4 bulbs over a year ago and they look good,were a direct swap, work good an are just as bright as the originals. No issues to date with them.
I can see just as fine with them as the original style for what it counts. Mostly did the swap for the more upgraded modern look.
Not to say that others are wrong with what they may have mentioned.....just saying that they work fine for me.
Here some pictures.
