higher wattage = more current in spark = more heat = higher arc = increased optics distortion = more glare

If the reflector/projector headlights are DESIGNED for use with 55w HIDs, then no glare. Otherwise, glare is present and increased with increased arc hight.

Increased halogen wattage doesn't change glare since the light is contained by the filament coil, in a HID bulb, an arc is produced between two electrodes giving no containment so the arc... arcs. More energy produces a larger arc. This arc displaces the light's position within the headlight changing the pattern produced.

Look at a Toyota Prius with factory HID and a retrofit civic, you'll see the difference. The Prius is designed to use HID so there's no glare.
