Updating HAG 225 Re 4/4

I had bought a used HAG 225 from eBay. I recently upgraded its decoder to the Marklin 60983. I am wondering if

1. the incandescent light bulbs in front and rear can be replaced with the LED option?

2. Can the lights be upgraded to the Swiss prototype option with the red LED?

3. Any other update that can possibly be made, updating the cabin and putting a driver in it?

Thank you Ruedi for the link. At CHF76, I find it a bit expensive. Will try to find a DIY fix, if possible.
