I recently installed a set of litronic headlights from a friend who sold his car and let me swap out his litronics for my halogens. I noticed that when he first turned them on before I took them out, that the lights self-leveled from a down position to an up position. Pretty neat. I know that this feature would not work unless they were installed at the factory. I put the lights in my car, and then tested them out. Everything seemed fine, and I think all is normal. However, I was wondering if since I don't have this self-leveling system, when I turn the lights on, do they turn on and point down as they did on my friend's car, or do the turn on at a default level, bypassing the swivel up feature?

Reason I ask, of course, is that I'm worried the beam is not pointing high enough as they don't swivel up upon turning them on. Thanks in advance.

Xenon is low beam and halogen is high. When you select high the low beam rotates up a few degrees to fill in with the high beam.

Since you do not have the control unit you do not have this feature, unless you buy it and install it.

There are others over the years who have done just what you did, so I would not worry about it.

Thanks Tool Pants. I was just curious because it seemed that when my friend turned his lights on, they started in the down position and the swiveled up to light up. If I don't have the self-leveling feature, then I would think the beam would point down when turned on and then stay in the down position, unless the lights somehow knew that there was no longer a self level feature, and thus ignite with the lights automatically in a default up position.

The leveling system uses stepper motors to postion the projector units. When switched on, the lights start from their previous position, motor down to the bottom end stop (so the system can self calibrate the projector position) then motor to the calculated level position. Where your lights are set, is anybody's guess as they will remain in the position prior to disconnection. This will depend on whether your friend's car was loaded/unloaded, on a slope, on high beam or being calibrated.

Most self leveling systems are set to a basic settting position by the factory diagnostic tool, beam set with car level and unloaded, then basic setting stored.

Thanks. That helps a lot. Before I removed my friend's lights, I had him turn on the lights in his car with the car level, and unloaded. Therefore, according to what you are saying then, is that the stepper motors then leveled the lights to the correct calculated level, and then stayed at that level when we shut off the lights. Therefore, it would seem that when I put the lights into my car, it would then turn on at the same level they were last turned off at, and all should be fine then.

Also, are the stepper motors located in the litronic light unit itself? Just curious. Thanks again.
