Thank you very much for the part numbers. Now I am able to ask my part supplier for quote.And sorry to confuse you that my car is Waterjet/XENON equipped from its(maybe her?) birth. My car, Lancia DELTA LHD 1.6D Multijet(GOLD SELESPEED) is running on a Left-hand Traffic country. The U.K., India, Australia, Japan, Singapore, Thailand… in these countries we normally drive RHD car since national road is Left-hand Traffic however, my delta is LHD(not RHD) and naturally possesses Headlights for LHD p/n as;OE p/n 51876359 HEADLAMP LH H1 Xenon - LHDOE p/n 51876363 HEADLAMP RH H1 Xenon - LHD Thus, every 2 years compulsory National CAR INSPECTION(similar to MOT in the U.K.) in my country meets slight difficulty to align the headlight beam, in order to avoid flashing against oncoming traffic, adjustment needs fairly low/left aiming so as to pass the test, in the result the night driving is not bright enough. So, I would like to solve this issue by swapping the headlights from Lancia DELTA LHD XENON genuine parts to Chrysler DELTA RHD XENON genuine parts. The project will be just XENON to XENON. Regarding the points you have kindly mentioned;" will need other stuff like the bulbs, different DLRs, ballasts, an ECU and maybe a wiring change and plus the washers and a different screen wash tank! and bumper!!! "I suppose/hope all of them including instrument display(=Expression of ECU) will accept the replacement. Only one thing, BIG anxiety is AFS system may work opposite direction or somewhere else..AFS ADAPTIVE LIGHTS(Adaptive XENON Lights) seen on pp.77/104 on Chrysler Delta OWNERS HANDBOOK issued in the U.K.As you know it works Headlight beam automatically aiming to inner direction of cornering using car info(velocity/corner angle/steering speed), would you please forecast some problem might be involved? Thank you for your kind cooperation.DELTA Headlamp on OWNER HANDBOOK.pdf
