Interesting but are they for uprating/updating or replacement of originals?

I would look at what cable slack you have first before investing in them as you may need to extend. Never seen them with fans built in before but similar ones are very popular mod on motorbikes but normally come with separate ballasts and prove to popular and reliable.

I'm gobsmacked by the complexity of a light globe.

H based LEDs with fans have been around for a while in an attempt to keep them cool.

 

You don't want to use them on the road as the glare they'll cause in reflector housings is terrible! Even in the marketing image, the LED low beam is putting light higher than the halogen high beam!

 

That level of complexity seems rediculous
