	~~Inner~~ door illumination is ~~done~~ by a LED module ~~that is~~ installed in door lining.		The inner door handle illumination is provided by an LED module installed in the door lining.
	The LED module contains a small ~~bulb while the~~ light ~~is directed~~ to door handle ~~over~~ on ~~optical~~ wire.		The LED module (A2208200321 for the left side / A2208200421 for the right side) contains a small diode
			that directs light to the door handle via an optical fiber.

			The black part of the LED module is universal, while the gray optical fiber is side-specific.
			The LED diode (3mm x 5mm) emits orange light and draws 35mA of current at 13V.
			A resistor, installed on the negative wire, measures approximately 300 ohms.

			\|}

			It is possible to replace the original diode with a larger and more efficient one
			that produces significantly brighter light while drawing the same current as the original.
			For example, the result below shows the use of a 3V, 5mm orange diode rated at 50mA, reusing the original 300-ohm resistor.
