Self-levelling lights

JFB · 06-18-2015, 01:23 PM

I recently had to pull both my headlights out to re seal them and change one ballast. Now, everything is beautifully back together and it all works as advertised. Until last night.

It was probably the first time I was driving at night since I did this maintenance about a week and a half ago and it seemed to my headlights were not lighting the road far enough ahead. It almost seemed they were angles too low.

Now I thought my headlights were self-levelling, and from that I took they levelled themselves properly to the correct angle to shine light the proper distance.

Could I have turned a knob snow here by accident which would have changed the angle of the headlights? If so, which one and how do I readjust it again?

Thanks.

park in front of a garage/wall. turn the car on and, if i am remembering correctly, you should be able to see the headlight adjust.

There are two factors at play here. One is the mechanical aim and the other is a the self-leveling mechanism which attaches to the front suspension and consists of a control rod, link, and electrical sensor.
