Hi, this is my first post and I really don't know much about cars. One of the puddle lamps underneath the passenger side views is flickering, and I think I want to replace it. Is there a certain bulb or lamp I'm supposed to replace it with or do I replace the mirror entirely? Sorry if I sound like a dumb kid or something. Thank you

 

It is an LED board; Which I'm not sure they are even replaceable. It might be possible to just replaced a diode or the board but youd need to take it to an LED specialist.

First id check the wiring and connection to make sure its not corroded or broken to start.
