I know how to remove the cover but there is some sort of plastic light deflector over the bulb. I see it has a place to depress it but since it is made of plastic I am afraid of snapping it off. Do you depress it and pull down on it to free it? Then is the bulb a 'bayonet' type? Looked in manual under replacing bulbs but they do not cover it or I missed it. Took car in for service and they left it on for about 5 hours. Thanks
