Headlight assembly. 99 Jimmy

Can anyone advise me on how to remove the headlight assembly on a 99 Jimmy please?
Actually I just want to replace the drivers side front park light & marker light, which are out.

I've removed the two black locking strips, that are easy to see from the top near the air cleaner. But the assembly still doesn't want to come out??

Don't want to break anything!

Thanks.... Roger :headshake

Pretty sure the grill needs to come out. Then the headlamp will be accessable.
