I've replaced a number of stock bulbs in my 2013 Prius v Two with LEDs. The light is SO much nicer and the energy usage is roughly 1/5. I thought I'd post the parts I used in case others are interested in doing the same. SYLVANIA LEDriving 168/194/2825 LED (Amazon): Front sidemarker, next to headlight (2) Interior door (2) License plate (2) Map (2) Vanity mirror (2) - (I haven't replaced these yet but this is the part I'll use) SYLVANIA ZEVO DE3175 LED (Advance Auto Parts, currently cheaper than Amazon) Dome (1) Luggage compartment, cargo (1)
