I am on day two of my 75k service and spent some time talking to the parts guys about the low beams in the RTL. We discussed the issues with the low beams and LED's not solving all issues with the low beams. We got to talking about Xenon's

Has anyone used Xenon bulbs in their RT's?
Do you feel they discolored the lenses faster than Halogen \?
Did the Xenon's offer any better illumination of the road and surrounds?
