I stumbled onto this guys YouTube page in his series of "How to" videos for the MK3 Focus.
He covers the following on his 2012 Focus HB:
1. Tail lamp removal
2. Tail lamp bulb replacement
3. Fog lamp removal and bulb replacement
4. Headlight assembly removal
5. Side marker and puddle lamp bulb replacement
6. Cargo area light bulb replacement
7. Air filter removal
Hope you all find it as useful as I did.
