Bests & Worsts Reviews from Amazon

Update - February 2018: The warranty for these bulbs says they're good for two years at up to 3 hours use per day. I use them about two hours most days on my long commute, so I thought I'd see how well the warranty works. Pretty darn good, it turns out. After an email to Philips, they requested some info (receipt, several pictures, etc.) that I sent off several days later. Six weeks later, just when I was going to email them again, I got a FEDEX package with a two-pack of the bulbs as a replacement; good way to keep a customer. Excellent customer service, so I'll bump the review up from 4-star to 5-star. The other original bulb is still going strong, so maybe my failed one was just an infant failure. Original Review: Well, on the one hand, these do a great job of lighting up the road. I live in a rural area with no street lights anywhere, and the light from these bulbs is crisp and white and a huge improvement over the OEM lights that came with my Mazda3. On the other hand, after just one year, one bulb has burned out after less than 300 hours of use, a poor lifetime as far as I'm concerned. The second bulb is still working fine, but for a "long life" bulb, this is not a good performer. I'll probably re-order this time, but if I continue to get short life spans from these bulbs, I'll move onto something else.
