Although the sidelights appear built into the main headlight cluster, the access section is actually through a whole in the wing of the car (but within the engine bay).
The light bulb is mounted on a longish plastic body that has a handle (for your fingers to grab onto).
The holder is a quarter of a turn type of device and will slide out into the engine bay once undone.
Sorry if this sounds confusing, but not many people would know where the actual side lights are located unless looking in depth.
so the side lights are NOT clustered with the main light bulbs in the main housing.
