HELP: LCI Halogens to LCI Xenons

Can someone point me in the right direction on the wiring changes that need to be done in order for the xenons to work with a car with stock halogens? I've purchased xenon headlights assemblies with all bulbs and such, and can code it myself, I just need help with the wiring and what needs to be spliced and such. Thank you!!

I did the same conversion that you are planning to do right now.

Just follow this DIY and you should be fine.

In the DIY, it shows Pre-Lci headlights, but the procedures are still the same with Lci.

Good luck!

I don't know if you did the LCI xenon retrofits, but do the LED turn signals need to be rewired/modded to work?

I did do the LCI xenon retrofits, but with the European spec headlights. However, the conversion is the same with the US spec, I believe, correct me if I am wrong, anyone else.

But I do know that the turn signals do not need to be modded for it to work.

Awesome! I think the only difference between us and euro spec is that us has adaptive functioning. Did you do the splicing inside the headlight or on the harness?

I did the splicing on the harness. A lot easier. Alex Alpine from Socal helped me with the wiring mods for the conversion.

Follow the Diy I posted earlier, and you should be fine. Unless you are doing the adaptive feature, then I may not be able to help you because I didn't go that route.

Ok thanks. Are halogens same for pre lci and lci? My car is lci halogens. And from what I understand is that I need to switch wires 5&6 (or do I tap them together?) and then tap 2&4 and then tap 7&12. Is this all correct?

They definitely look different and the fitment is not the same, but they function the same way.

Tapping wires 5&6 will enable the bi-xenon feature, which the Euro spec xenon lights have. The US spec has the inner halogen bulb that functions as the high beam. Not sure what spec lights you have. But I think tapping 5&6 will have your high beam function (Might need someone to confirm).

Tapping wires 2&4 is correct.

I am, however, not sure about tapping wires 7&12. I don't think I tapped those wires. Wire 12 is for the side blinker.

It all comes down to what spec headlights you have (US or European). US headlights have the inner halogen bulb that functions as a high beam. European headlights do not have the inner halogen bulb, and has that inner "projector" blacked out. As a result, it uses the bi-xenon feature.

You never told me what spec lights you have
