hi, has anyone changed the complete headlight with the OEM tungsten bulbs, to the Vignale headlight unit with the led DRL etc, if so is it just a plug n play using existing plugs or does it require a ballast or it just isn't compatible?

 

 

 

The adaptive units with the LED DRL's is a completely different headlamp unit that also needs a separate/different wiring harness, the adaptive headlamps have their own ECU and there is a fair bit of coding of other ECU's in the car. That's why since the car was introduced, into the UK in 2016, the only feasible option to improve the 'standard candle' headlamps is to replace the actual bulbs with individual like for like LED's. The option for this headlamp unit was a £1300 factory fit only.

If you do a search on this forum, you'll see the many conversations (and LED replacement choices) about this over the last 6 years.

thanks Simon, I have read a few good threads about the bulb replacement and had decided on which bulbs to use, so looking like that the least hassle option, I kind of thought there would be a bit more to it, than just replacing the whole headlight.
