Rear light Facelift Limo (inner lights should be included)

Hello, I would like to use the inner taillights as normal driving light and fog light, is there already something finished or do you have to make something yourself? So fog sparks anyway only the driving light still have not thought of there such an incandescent lamp as for the brake light, is worth the effort, has someone done this already (photos?) and what does the TüV say about it?
