Reading through your previous posts, I'd guess your getting fed up with the retro fitted lights not working properly in your R lookalike.
It is possible to get them working, you just need to find someone that knows their way around the coding. There was mention of someone that had done this successfully in VW Driver a few months back. I'll look it out later.
If I was you, I'd stick with the lights. If you swap back to halogens, the car will look even more of a fake than it already is.
