I did more of a mix/match set up.. for domes used wedge bulbs (194's) of my choice.. you have two main domes and each dome has two reading lights.. doors have 4 puddles.. wedges also but i went with bimmian lights on these.. complete replacement with SMD panel very nice pure white light.. for footwell the replacement housings did not work as the plug is different.. not just a two wire.. at least on '15 model they are LED from factory.. soft white with amber which stay on during night.. (similar to amber dome light factory on nearly all BMW models). For footwells I opted to insert a wedge bulb directly into OEM socket and use OEM housing :-) This way i can put them back to stock in a heartbeat..
For the trunk, i did LED light bar as no matter what festoon or wedge you put in there its not enough light and i wanted day time :-)
I've had mine for 7 months no issues so far..
