1. Tabs are not important since BMW sells kit to fix them (around $5-7 per tab).
2. Agree, self leveling is a waste.
3. Not necessarily, HID use 42 watts during normal operation (35W for the bulbs and 7W in heat losses), stock H7 halogens use 55 watts, so the difference is not substantial. Depending on your particular case you may or may not get “bulb out message”. I was confirmed by few members here. So I suggest trying before purchasing any resistors which will create additional load on the harness.
4. Correct my H7 sockets were little bit bigger but I fixed them in 2 min.
5. Most X5s has Philips D2S 85122 which are 4100K bulbs. But color change over the time, new bulbs rated at 4100K and then it goes up to 4600K after 2000-1500 hours of operation. So here is change in brightness:
100% at 0 hours
90% at 200 hours
80% at 1000 hours
75% at 1500 hours
70% at 2000 hours
That’s why I recommend new bulbs.

1. Make sure that tabs are all in tact since these are what holds the headlight assembly in place. Look for deep scratches and possible condensation marks inside the lens
2. Forget about the self levelling motor as you can adjust the beams manually. This feature is a big job to install plus $$.
3. Even OEM hella Gen3 ballasts would give you the bulb out error mesaage but their are resistors that are plug and play available to eliminate this. Ask one of our members Zulu95 (Paul). I ordered a resistor from him simple 10 minute plug and play. error message is gone.
If you are buying OEM headlights w/ projectors then only D2S bulbs will fit.
4.Stay away from H7 HID conversion kits. It will not fit the OEM bulb socket. Look for Hella Ballasts (Gen 3 so you don't need an igniter) w/ the bulb adaptor and possibly bulbs itself. If you do this simply 30 minute install.
5. I could be wrong on this but BMW D2S bulbs are rated between 3800K to 4300K
Hope this helps
