When turning on lights on CLS, what type of bulb replaces Yellow parking light?




2007 CLS63 -- same thing as the r230 SL I believe. When you turn the headights on, on the inner lamp there is a small bulb that lights up orange/yellow in color and looks bad next to the d2s xenon HID low beams.
WHAT TYPE OF LED replaces this that is ERROR FREE?
I see some people have this, but can;t find any sources.
Thanks for the help!
I picked mine up from a local shop for $20 (pair). They shine a very bright and clean white. A huge improvement (esthetically) over the OEM yellowish halogen versions. Install took not even 10 minutes.
Here's a shot if mine...
