looking for this. it is the light that is in the half round silver handle that is found between the door handle and the speaker.also, link to electrical diy for power wiring?
Never did find an OEM part number (not that I looked hard)
I simply purchased some prewired LED's (if your in the UK I can post you some as I received about 20 in a bundle) and they fit in the predrilled hole perfectly. You need to make a secondary wiring hole in the door handle and also in the door card and a connector between door handle and door, so you can disconnenct it for door removal.
You also need to add an extra power cable from the footwell light wire through extra pins in the door harness connector, so they are controlled by the auto dimming and on/off of the car. Pick up any brown wire as the earth and make an internal harness.
I did this as a part of a project to add puddle lights, interior door handle and exterior handle illumination.
