Lithtronic upgrade WITHOUT the wiring harness ?

[siddharth]

Hi guys,

I'm looking for clear headlights (another thread) and someone is offering me a set of litronic headlights for a good price. However he tell me "I will explain the wiring harness to you, and why it is not necessary.". I've not yet spoke to him and wanted to throw the question to you guys before that. As far as I know if I just slide these in place of my regular lights, I'll get xenon for low beam and halogen for high beam - no xenon meets halogen in high beam - but that's a guess.

What do I really lose by not installing the wiring harness as I upgrade to litronic ? I'm also assuming that without the wiring harness there is no control unit too, right ?

Fianlly, if I were to install the wireing harness / control module, how much are they for and are they easy to install ? BTW my car is a 1999 996 C2....

thanks in advance ! Lots of questions ... :)

hmm ... it appears that without the extra wiring harness and control unit, I lose the ability to rotate the litronic bulb to put it in "high beam mode". As per my understanding, the litronic system has

1. one HID/xenon bulb in low beam position. This rotates to become high beam

2. one halogen bulb in the fog lamp. This is purely a fog light.

So am I right to say that without the extra wiring there wouldn't be any high beam at all, right ?? That'd be bad ! I could switch on the fog light, but the basic trajectory of the high beam would be missing ...

Please correct me if my thinking is awry ...

thanks,

Sid

Sid,

You are awry.

Fog light is not a part of this discussion. The Litronic unit has a Halogen hi beam and a Xenon HID low beam. When the electronics are connected during the retrofit, the HID low beam will rotate up to join the halogen hi beam to increase visibility (significantly, in my view).

There are also fog and turn bulbs in the unit, but they are not involved in this question or process.

Kim said it well.

When you select high beam the xenon low beam rotates up a few degrees to fill in with the halogen high beam, if there is the control unit hooked up.

Without the control unit you will have 2 beams that are not combined to be at the high beam level.

No big deal but this is not how it was designed to max out the light output. But, plenty of people do not install the control unit or if they buy used lits they do not have the unit to install.
