I am having problems with a particular corner on a car I'm modeling The top picture is where I am now, and the bottom picture is where I want my topology. I basically want another two edges horizontally across the front bumper, but also want an edge loop around the light. Any ideas on how to achieve this? (or really, any ideas at all as to how I could model this correctly?

I'd suggest adding a couple more edge loops to handle these spots:
