How are these H4 LED bulbs? They seem to be a favourite among motorcyclists (
http://lightingmycycle.com/2014/08/2...lb-hands-down/). They retain low and high beam, which is nice. I assume they are not as bright as drop-in HID's, but that is probably a good thing in regular reflector housings, as long as they are at least on par with standard halogen bulbs.
Do they actually have a fan inside? Is the fan loud? Is the output just false advertising, like blue-coated bulbs or LED tower bulbs?
