People these sales are scams, the OE equipment claimed to be part of these kits are not even available wholesale from the manufacturer at those prices. They are fakes/knock-offs. These are nothing more than Chinese purchased kits, not only are they misrepresented they are also damaging the image of a highly reliable Company. Go to their website, look at the pictures of the supposedly real Hella ballasts and the supposedly real Bosch ballasts. They are the same design and the fake Bosch ballasts carry the real philips ballast part numbers, wouldn't that be a coincidence!
Don't let the printing on the ballasts, the stickers, and packaging fool you, its all fake! Hella and Bosch both are very well aware of the ramifications of damaging their reputations by selling illegal conversion kits, that is why they don't!
