just got a 2010 Prius - need advice

Changed out the washer pump today and knocked that one off the punchlist. Accessed through the driver side inner fender which made it pretty easy.

3 of the 4 metal screws fastening the bottom piece (between bumper and inner fender)snapped off at the head which wasn't great but not surprising.

Son mentioned that the headlamps are pretty dim. The plastic lenses are cloudy--could try polishing them but have found that doesn't last too long. Anybody have a good source for aftermarket headlamp assemblies? Ones on Rock Auto are $75 a piece...
