Hi, i spent 2 hours at the dealership a few months back, we were testing to see if the LCI bulbs would be bright on the pre-lci. Unfortunately no. They are just as yellow! The LCI has built in LEDs aswell i think, that make it so bright.
As for the dealer saying the LCI bulbs will run hotter - thats rubbish because now if you order new bulbs for the Pre-LCI they have been replaced with the same bulbs as the LCI! Both have exactly the same part number
