Aftermarket/Custom Lights?

Hi, I am new to the GEO line but the GF has a 95 prizm lsi and have seen them with custom head and tail lights, but I have not been able to find them online, all I can find are OEM replacement lights.:runaround:
I have been seeing, in my searches, that people are using he corolla headlights of that body style.
do these work without modification or is it a pain to swap?

Thanks in advance for any input.
