HOW TO: Enable US Style Sidemarkers - & a question about light mapping!

Hi guys.

Firstly, how to enable US Style sidemarkers for non-US spec cars that do not have the small yellow side LED in the headlamps:

There is a wert value for LAMP_MAP_PARA_SATZ_03 and LAMP_MAP_PARA_SATZ_04 which enables US style sidemarker lights, which is "BV_F025_wert_01_BLKgedimmt_als_Sidemarker" for both of them. This enables the front indicator to come on statically at low voltage when the light selector switch in the car is on anything other than '0' (or 'A' in the daytime. It comes on at night with the rest of the lights). On the 6-series (which also uses F10 from a coding point of view), this illuminates the inner pair of turn signals.
If the turn signal is applied, it will temporarily switch off the sidemarker light for that side of the car (so it can clearly flash yellow light on and off), and it will go back to sidemarker mode when the indicator/turn signal has been switched off. This also applies to hazard lights.

Now... For my question:
The default werte values for these two functions (thats werte with an e at the end!) are {00,00,00,00} and {00,00,00,00}.
However, when sidemarker lights are enabled, the werte values change.

I do not have access to the car right now, so I cannot list what these new werte values are exactly, however I wonder if anyone could tell me what each of the 4 numbers (I presume they're hexadecimal numbers) signify? I tried playing around with them by changing their values, but the light's behaviour either stayed the same or was disabled. I was hoping that one of the values could change brightness as I would like to dim them!
Does anyone know how to dim the brightness of these?
