The first set of SilverStars I had lasted just over a year. The second set about 2 1/2 years. We'll see on the 3rd set. It'* been maybe about 9 months so far on this set.

The SilverStar headlights do great job under normal conditions, but in my opinion, the color of the light doesn't work as well with wet or rainy conditions. So, I leave my fog lights as standard color bulbs to improve visibility when things are wet.

I had a short lifespan on my first set....a little over 6 months. Took them out and put in the OEM bulbs that came with the car. Wrote an email and they said send them back and sent me a new replacement set. I'm now on the replacement set. I'll see how long these last. 3 months so far.
