tip: if your hella bracket has the foam rubber pad between it and the light (mine did, if not, it comes with the stamped steel ff1000 bracket), re-aiming is very easy since you will have clear indentations in th foam rubber to guide you back to the good aim spot.
Optilux is NOT the good stuff. That's the junk they sell to compete with all the "tuner" crap they sell in the backs of magazines and parts stores.
