Hello all. Is anybody aware of the bulb type for the daytime running lights (non LED) in the 2011 model C class. Also, how is this bulb accessed? From the front or via some access panel in the wheelarch. The handbook makes no mention of the bulb type for these lights and I've had a push and pull on the outer of the two light housings but don't feel brave enough to introduce it to a flat headed screwdriver just yet! Many thanks in advance.
