Litronic (Xenon) beam effectiveness...

[Boxtaboy]

Does this look right to you guys with Litronic or HID conversions? I never really thought too much about it until I visited a relative, and drove their Benz with factory xenons, and noticed their beams seem to throw much more light (more intense and wider). Just seemed so much better than the Litronics in my Boxster. I checked aim recently, and they seem to be height aimed correctly 25 feet from wall, although I didn't try to adjust the left/right throw. The original D2S xenon bulbs from 15 yrs ago are still in the headlamps. Never changed them cause they are still burning...do they get dimmer with age? Or do I need to adjust the left/right positioning as well? Was told to stay away from this adjustment as it's not easy to do?... Or am I just imagining things and the below throw looks ok?
