Seat leon halogen to led

[East Yorkshire Retrofits]

Why you said that? Also did you get the wiring adapters? Or did you made them? I found some options at eBay but the costs variety a lot just in case you want them or how long have you been advanced

It isn't just wiring adapters. You don't even need adapters, just change the plugs. You'll need terminals and a crimping tool

Facelift headlight wiring is completely different to prefacelift

You probably should have a little look at the above, it seems to imply that a whole unit change is ok but if the self levelling isn't working then you are in for an MOT fail. So I guess you must make sure that works within the unit.

Not even convinced you can have LED/HID lights without auto levelling by law but that might not be totally correct. A Mazda engineer told me that as i complained that my HID lights were utterly dangerous and why could I not adjust them in the car. Well without monkeying around the back of the headlight with the ridiculously awkward adjuster screw that is

So you've done the necessary wiring, fitted the necessary level sensor & range control module followed by the necessary parameterisation & coding?

 

[mk3leon]

I do it wothout the leveling i use tje wiring patern and plugged in and the headlight works except the parkimg light

Ah, enjoy blinding everybody then

To fit pre-facelift headlights to your facelift Leon with no levelling, you don't need any wires or cancellers. Just pin adapters following the new pinout (see image bellow) and coding (the same coding required for a pre-facelift Leon).

hi, I have a pre-facelift Leon with halogens, and I want to retrofit facelift LEDs. Will it work if I do this (of course in reverse)?
Thanks

Hi All,

I to have a Seat leon mk3 1.2 TSI with halogen headlights .. wish to change the front ones to LED's. Can some one provide me a list on what I need to buy? it cant be simple just for a pin adapter and coding no?

Help is really appreciated. As being that Im from Malta. To find LED headlights is quite difficult and the only option is buying them from eBay paying high shipping and high import charges!

Thanks in advance!

what about for pre-facelift or facelift led headlight to pre-facelift halogen headlight for a conversion?

Don't bother - as well as the conversion without any self levelling being both dangerous and anti-social, LED lights might "look" better, but the light output is no where near as good as the standard halogen. And your car wouldn't get through an MOT anyway without the full levelling fitted and working.
My last Leon had factory halogens, and they were atrocious in bad weather, along with a very poor spread and throw of light. My current Leon has halogens, and the lights on this, with Philips Xtreme vision standard 55W upgraded bulbs (perfectly road legal) are vastly superior to the LEDs on my previous car.
If I had to change my Leon for another, I wouldn't for one second consider buying one with the LEDs now.
