Replacing rear camera flash/flashlight

My wife's phone was run over by a car. Amazingly the screen was not damaged and it retained most of it functions. The rear camera lens was cracked, but initially, the camera still "worked" though it was completely blurred out.

Now when the camera app is opened for the rear camera, there is only a blank screen, and the flash/flashlight will not turn on. I figure I will need to replace the camera and lens and have seen where they are available.

As to the flash/flashlight, I have not yet been able to figure out the part name or locate a source for it. Can anyone point me in the right direction? Thanks.
