Suggestion
Also unlike incandescent bulbs where lumen output goes down with use, HID bulbs generally tend to suffer from more color shift over time than lumen degradation.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

While i have the Litronic on my 04 C4S, i do find it not as bright in today's standard. Has anyone swapped out another pair of bulbs with better lumens?
I searched, but a lot of threads are about regular bulbs going to HID, what about Litronics to brighter bulbs? is there any choice?
The sucky projectors are more of the limiting factor. There's been members here that have taken it apart and sanded/polished the projectors to achieve better lighting results. Either way, whether getting new bulbs or sanding stock projectors might only achieve marginal results depending on what types of improvements you're looking for.

that sucks... i went on a drive with my buddy who has a 997 and his lights are brighter... i was hoping there is a magic bulb out there i could change to... LOL
Bulbs wear out over time too and don't put out the same level or temperature of light as they do when new. Just putting new stock bulbs in could make a world of difference too.
Do the stock litronic bulbs last a while? Im on my originals and its a 2001 car. Plan on removing the headlights to polish them so may replace them with a stock pair.
My 2001 C4 Litronics are not as bright as my 07 Mini with Xenon. (same thing BTW). Neither are as bright as my after market projectors on my M3 dang near daylight.
I went with the OE bulb. I ordered it online from Pelican Parts. It's tempting to order a "whiter" color temperature like 5,000K or 6,000K as opposed to the OE 4,300K bulbs. There are many posts on this and many things written about it. While the whiter bulbs have an appealing look, they compromise when it comes to lighting performance. This is especially true in inclement weather with limited visibility conditions. 4,300K its the best way to go for optimal lighting.
I do still feel that the HIDs in my 997 are slightly better than they were in the 996, even with new bulbs. It may just be the design. The HIDs in my wife's Audi are better than the HIDs in the 997. I suppose the technology continues to improve.
I'd agree with these points, though I'd add that ride height plays a part too I think. Our 01 996, 07 328xi, and 13 958 all have their respective HID variants. The Cayenne is the best of the bunch by far followed by the BMW and then the 996.
Even with old bulbs/ballasts and occluded housings the 996s are still better than any Halogen headlights.
