Received and installed my H4 LED headlights yesterday. They are 25w, 1800 lm, 12v.
These kits are available on eBay for now 4-5 months. Paid 65$ for it, plus it was free shipping. Upgraded from 45w Sylvania EcoBright to 25w LED. The seller say that they are 6000k but I don't know if its real. I can say for sure it is bright white.
They fitted in the socket but the end of the light unit were too short so I was unable to fit the fans properly, so I came up with an idea of extending with threaded rod and nuts so I could fit the fans. Be carefull when you buy things off the Internet especially if it comes from China, you might not receive exactly what you expected.
