the E83 headlights are a complete unit. In order to get into them you basically have to bake them open..which I wouldn't even try..

There is a option by buying something like this which is what i have on my 08 X3. Works well. Keep in mind this utilizes the original halos inside and just changes the bulb color from orange to white. https://www.amazon.ca/KATUR-Xenon-65...86441503&psc=1

These will still be controlled by the onboard LCM module on when they come on, only when headlights are on. In order to activate them as ALWAYS ON (kind of like DRL) you'd have to get a bypass module which is like $150 otherwise your halos will only come on when your headlights are. Its not an option that can be coded on the E83 as the halo ring in the headlights is not its "own" entity for programming like some E90s etc.
