Does anyone around here know how much work it is to install the fog lights yourself? Thanks! Edit: Found the post for whoever's curious. 2010 Prius Fog Light Install [Retrofit] | PriusChat
I just wired mine to be DRL up to the fuse box. Before i had it relay in w/ the low beam so as soon as headlights are on, the fog lights are on too.
I used some pigtail sockets to tap straight into my low beams so they come on together. Didn’t bother with the switch or relays since I’m using LED’s in both. Works great and no need to run wires into the cabin or splice the factory wires.
