For puddle lights:
An original retrofit for the front door involves removing the door card, cutting-out the hole for the puddle lights, then fitting the lights. You can either fabricate a loom that connects the lights to the door control module then activate it on STAR, or you could simply run a wire to the door switch which will save fabricating an original loom and STAR activation.
For the rear, the process is similar expect there's no room in the rear card door to fit the puddle lights, instead you'll need to get new door cards with hole for puddle lights.
Said that, some cars (coupe) can with the puddle light fitted but no bulb or loom - in this case what is needed is a bulb, a loom, and STAR activation (or instead connecting to the door switch etc).
