Osram Nightbreakers are really good bulbs, fantastic output and light color, however, the durability leaves a lot to be desired. I replaced stock H11's with the Nightbreakers last June, and one went out last Tuesday, and the other 2 days ago. So, I got about 7 months out of them. I replaced them with the stock H11's and am about to order a couple of H9's and do the H11-to-H9 mod. I feel really comfortable with the mod because the headlight module has a built-in full frontal bulb shield inside. If they didn't, then I would buck up and get another pair of Nightbreakers.
