I had similar bulbs Philips brand on my Toyota Yaris. One was burnt and he had to change both. This is where things get complicated. Moreover, we must wear gloves to take the bulbs. After more than 40 minutes the bulbs are replaced. The galley, automakers thank you. It would change the perspective when the bulb is dead. These bulbs have exceptional light quality and worthy of xenon headlights (I compare to what I had on a VW Touran). I hope that life will be as long as possible. This is the main problem of this type of bulbs. Competitive price offered by Amazon (impossible to find better elsewhere). Fast delivery bulbs and perfectly protected in the package (I was hesitant on this point).
