I have never had any bulb out errors mate with them, i went for the "Ultimate Kit" from HIDs4u.co.uk, they supply the bulb holder free of charge with that kit aswell, but put a reminder in the delivery notes as they forgot to include mine.
I powered them from outside the headlight unit, I know some people have removed their bumper and taken their headlights out to get into the connection but save the hassle and do it the way I done it, 1 hour max to do.
Let me know if you order them up and I will get some pics and a wee "how to" for ya.
