How do I replace a BMW daytime running light for UK BMW 3 series Tourer?

The daytime running lights/ halo/ Angel lights- whatever you choose to call them on my UK BMW 318 Tourer are not a 2 minute job to replace. YouTube only has US video with different lay out to my UK model. Any advice from anyone out there on how to do it? Costs quite a few quid to get a garage to do it. Thanks if you can help. Mark
