I do notice my driver side bulb upon start-up flickers two times to a red color, and I assume it's the red burner core (unique to Philips) that is being vaporized inside the bulb casing upon warm up. I don't think this is the flicker problem people are facing when the bulbs fail to ignite at all.

Overall, good investment and the lights add positive aesthetics.
