Xenons seem to be dimmer with time

Perhaps it's my imagination but it seems that after 5 years the Bi-Xen's are getting dim. Specifically the low beams.

Am I imagining?.....

Nope, you are not imagining. Xenon bulbs increase the color temperature as they wear out. As a result, the number of lumens the bulbs output go lower.

If you think it's too dim, I would highly suggest buying new bulbs and starting the color temp to 4150K or 4300K again, which has the maximum lumen output.
