I just received them and put them on. They are slightly brighter than the GP Thunders I put in 4 years ago at $16, but these are LED and those were not. If you want LED, these are a good upgrade to pre-LCI stock. As expected, the outer rings are not as bright as the inner rings - the way the X5/X6 halos work - they project the light source from the inner to the outer rings with fiber optic tubes.

EDIT>> pic added but the right side came out blurry so it's a little yellow... the left side more represents the actual brightness at dusk. I may take better pics tomorrow.

One additional note, at nighttime, these halos are really bright, which is a big improvement to the GP Thunders I had. The halos seemed to go to low power when the headlights came on, but not with these.
