Hi all,
thanks for all the replies! sorry haven't been looking at this for a while. Just to answer a few Q's - Yes you can sill adjust the dip with the roller inside the cabin - i had mine calibrated on highest setting so that i can manually dip them if the car is heavy loaded. I guess you could retrofit the auto level sensors but i cant find a how-to on this.
The units I installed are HELLA ones - but as far as i can tell the only difference between these and the cheaper DEPO ones are that the bulb holders are at different angles and you may be required to do the "6 o'clock mod" on those if fitting HID's
Anyway - so far so good no problems at all!
