park light replacement bmw 745li 2004 on 2004 BMW 745Li

How to replace front 2004 bmw 745li park light bulb the round one around the headlight

Asked by for the 2004 BMW 745Li
The front bumper is to be peeled back/removed and headlight removed.
The parker bulb is fitted behind a cover at the bottom of the headlight
so I need to remove the cars bumper to change a parking light bulb?
I was told this as well by a dealership... very expensive. Are there directions somewhere for "peeling" back the bumper??
