99L1764

I just bought the car wear crystal eyes headlamp set, for the 99L. Don't know whether it was a mistake or not.
How in the *$&$ do you aim these things?

The factory lamps slide in and out easily, while I can't seem to line the new ones up without really screwing up the adjustment. I must be really stupid or something. (probably for buying them in the first place)

And, what is the final beam pattern really look like? I got them in with much fiddling and swearing, and quickly drove the beast out of the garage and light was scattered everywhere.
