Standard because the style matches the silver reflectors more when they’re off and the LEDs are all close and bright enough, you’ll barely see the individual light sources.
Opaque are a solid “sand blasted like” white around the ring so they’re a lot more highlighted in white when the halos are not on. But if you like a super uniform light spread then maybe that’s for you.
Crystal are closer style to F80/F10 angel eyes. Much more modern but the depth of the rings require dremeling the inside headlight trim to fit.
All ZHPs are high. It’s in their nature. [emoji23]
