Just share some of what I found for the LED headlamps comparing OEM headlamp and the Initiale version.
LED
Xenon
Original
The above images are from foroclio forum.
Xenons are a direct fitment for our original headlamps, as they have the same socket(2 numbers) but they are only available for LHD and they cost 1200 euro per set
The LEDs on the other hand has 3 socket instead of the current 2 socket, due to auto headlamp leveling, which would have a sensor (I assume at the rear of the vehicle like the Megane) , which would mean they have a chance to be connected back to the ECU. Our phase 1 clio does not have canbus, so the new clio phase 2 might have canbus(Different ECU?).
I am not sure whether just ignoring the headlamp leveling socket would allow the headlamp to even light up, I am not from the UK so I cant really get to check on the new phase 2 clio to check on the actual wiring for the sensors whether they actually go back to the ECU or the headlamps directly or even where the sensors are actually located.
Those who would like to try, below are the part no :
N/s headlight - 260606051R
o/s headlight - 260105517R
Height Level Sensor - 538214824R
Many thanks to
CEDGE73, for helping me on the part numbers!
