2015 corolla s

hello guys/girls My headlight bulb recently burnt out. And I was wondering how to fix it. I’ve read that I’d have to buy the whole head unit to fix it or i can replace the bulb by taking off the head unit and taking it apart. But i really don’t know how to. Anyone in here know what to do?

hey i have a 2015 Toyota Corolla s. I am running Rockford fogate component speakers and 2 Rockford fosgate 6x9 in the rear deck. I also got 2 10" type r w/ a Rockford fosgate mono amp. I bought a 4 channel alpine ktp-445u power pack to power my front and rear speakers. have any of you installed...
