Where is the fuse location for Renault Megane inside Fusebox beneath bonnet. Trying to locate Headlight fuse?

There are two fuse boxes on the megane, one inside the glove box on the left hand side just pull the cover down. The other is located at the side of the battery under the bonnet, it is under a black cover the first cover comes off easily (two screws) but I am having difficulty getting the second cover off as I need to get at mine, this secind cover needs to come off to change the fuses, you can see them but not get at them. If anyone can tell me how to remove the second cover I will be grateful.
