Replaced with aftermarket halogen foglights.. YES - but most aftermarket lights do not have the correct bulb shield to reduce glare as the OEM do. Clear 04 09 Prius 04 07 Highlander 04 05 XA FOG Lights Lamps Complete SET | eBay OEM style have shield. Replaced with aftermarket bright halogen foglights... depends on what you define as bright. This was brought up on a recent thread: Easiest/brightest fog light upgrade for 2007 Gen II | PriusChat Popping in some HID bulbs will do a pretty good job. Best method IMO is to do a retrofit as I did.
