Sylvania h11 headlights for 2013 Prius v

H11 seems like the correct bulb if you do not have the LED light option. Another possibility is Philips X-Treme Vision H11:

If you click the Buy now button underneath it shows links to Amazon and Pep Boys. Seems like Amazon has the best deal right now @ $26.99 (I choose ships from and sold by Amazon).

 

2013 v wagon. 10mm socket, short extension and a ratchet for the passenger side. Move the hose out of the way and hope your hands are small enough. Driver side is a snap after the passenger side. You might want to start there to learn how the bulb disengages from the housing. Wear latex/poly gloves so you don't get prints on the glass.

When the oem passenger side bulb died I replaced both with Sylvania Silver Star H11 Ultra's that lasted 10 months (on vacation and got a warning ticket). Bulb set number three lasted just slightly longer, once again passenger side first. We use ours as DRLs so they're almost always on but the bulb warranty is one year and the place I buy them honors it with a smile. I keep my receipts and packaging in the rear compartment, along with a spare bulb and everything I need so I can swap one in if I want to avoid one of those "friendly law enforcement reminders".

The Ultra's have a good light output but at ~50,000 miles don't seem to last that long under our usage. If set number four survives close to a year I'll likely just warranty them early.

 

I just asked the guys at CandlePowerForums Transportation, Automotive section about upgrading the H11s on my '14 Scion iQ. They recommended a modified H9 bulb. Might be good to go over there and ask.
