Installed on a X6 2012 BMW - 40w - Very tight area to get bulb out. If you have big hands you will find it difficult. Went to my local garage with the LED bulbs that cost me £54. He told me it would cost £40 to replace each bulb and I could bring the car tomorrow. I then came online and looked at this video and realised my garage had lied to me as he did not have to remove the headlamp as he told me. Took 10 mins thanks to this gentleman and saved me £80. Thank you Sir.
I'll be interested to know if these work long term. Just changed mine to LEDs Mine had a little box with a resister added to it. Had to fiddle around to get the little box and extra wiring in the compartment.
