F10LCI DRL half ring turn yellow

[tommy_tan]

Hi! My F10 LED DRL half of the ring turn yellowish while the other half was white. Is it degradation of the DRL module? If change the module, need to take the whole bumper out to take out the headlight to access the module. Anyone has similar experience and remedy?
Thks!

just change the headlight,not the module.
