Right, today myself and a friend installed my new H7 LED's. I have done a comprehensive right up on a BMW forum as I no longer own a Ford which took me ages to do. Call me lazy but I simply can' be bothered to write it all up again on here and other forums I'm on. Follow the link below and hopefully it'll take you to the thread. There is also another review on there from another member who installed similar ones to me. For your information these bulbs were fitted to a 2010 E91 BMW 330d that has halogens fitted as standard.
Apologies for not doing the write up on here as well and I'm sure some of you will think it's a hangable offence to visit a BMW forum, but do go and have a look at my findings as I believe they are very informative.
For those of you who don't want to go and have a look, let' just say the install was a bit of a ball ache but the results are great! Nice crisp white light with a good mot friendly beam that won't dazzle oncoming traffic. Very very impressed!
