I bought this before looking what my Prius had. One of the lights had gone off after about 65000km since September 2009 - I keep my lights always on (I do not have LEDs DRLs) on my Prius 3rd Gen 2009, and I turn them on / off at least once every day, 6 days a week. to my surprise, my Prius mounted the same exact light bulbs. Interestingly, the Philips website does not show this light bulb in Their product portfolio. The packing is a bit "weak" to old to halogen light bulb, but Amazon's packing was good enough to avoid any damage. These are, for me, really long life / heavy duty light bulbs. (Waiting for a plug-in LED replacement cheap :))
