Mine are holding up fine. I'm using the Philips X-treme bulbs which are rated to OEM specifications (55-65W). The difference is the upgraded harness enables the bulbs to operate at the full 55-65W rating.
How often do people flash their high beams at you? Strange that lately I've been getting "flashed" for my stock halogens. Could be due to the area where I'm at and a large percentage of country bumpkins, I don't know. Pissess me off to no end though.
