Leds operate by turning on and off at such a high rate, the human eye doesn't really see it. That's why they flicker during videos unless shutter speed is dealt with. Ideally u want a set of leds with canbus built in. This should keep visible flicker and dash warning lights away. Also won't need to change settings internally from halogen to led. But not all canbus bulb replacements are good. Took me some trial and error to find what worked. That's not to say that some cheaper bulbs are not good. Wattage draw can also play a role here with flicker and warning lights. If u keep wattage at or near rated wattage of halogen, shouldn't have an issue. Once u get to half or less, u may see those issues arise without canbus, especially the hyper flash with turn signal.I believe all leds flicker to some degree, it is impossible to see most of the time but as they run on alternating current they are constantly turning on and off, shows up in videos.
