Headlight Adjustment Methods?

[Desert Donk]

Anyone know how to adjust headlights on an 85 Bronc? I remember years back seeing some tool that had suction cups that attached to the lights with leveling bubbles. I have also tried just parking on a dark street and making adjustments until it kind of looked good. But I get folks flashing their lights at me or I get them too low. I'm looking for a way to get it right.

Thanks.
