I've had the taillights on my 2007 Prius burn out 3 times in the past 5 weeks. I took it in to the dealer, I assume they hooked it up to their computer, and the computer said there's no problem...two weeks later the bulbs are out for the 3rd time (every time I've changed the bulbs myself) The one on the passenger side always goes out first (don't know if that's helpful information or not). I've noticed this problem a lot in the forums and now see that new Prius's have LED clusters for the running taillights. Are there bulbs - brand, voltage, LED or otherwise - that hold up better? Am I looking at a grounded wire? Would the connection be corroded (and if so, how can I check and/or what can I check for myself?) Basically, not sure how well I trust the dealer to actually look for a problem vs. just changing a bulb or hooking it up to their "trusty" computer again, and I don't want to waste my time if I can do something on my own. Any help is appreciated. At the very least, I try not to be the car-illiterate damsel my dealer is so set on stereotyping me to be, and it'll help being armed with some information before I see them again!
