i have zero issues with aiming mine and the glare isnt bad either...it has the black line that cuts off the glare just like factory projectors do..thats what some of the cheap made ones do not have and cause all kinds of glare..the brights have the most glare because the brights have the reflector in it just like factory ones do..that where the most glare comes from when u put hids in factory headlights also..in my experience as well as my friends

Now on the other hand the ones i put in my 02 silv i just sold was a bitch to aim and had wayyy more glare..those are kinda shitty but the halos were brighter on the 02 than my 08 but its 2 diff brands...i really enjoy mine on my 08 i work nights and i had 8ks hids in the pics and switched to 6ks which are much much better for driving at night it has more white
