Hey. I have created other topic but no one seems to answer me so please answer me here. I'm going to buy SFH485 leds and I just need compatible resistor. Could you guys choose me one of them? I would be appreciated if you would choose them from there: http://int.rsdelivers.com/catalogue/search.aspx?query=resistors&Family=3350

Connect them in series with a resistor anywhere between 30 and 100 ohms for a 4 AAA battery pack. The lower the number, the brighter the LEDs will be. Any of value in that range should work fine and will give you good battery life. (The higher that value, the longer the battery life. The lower the value, the brighter the LEDs will be.) You may have to experiment a little bit. Brighter isn't always better.

Thanks for your help guys. I ended up of going to my local electric store. I bought highest angle IR leds (17 degrees lol) and sanded them a bit. I also bought some resistors and battery holder. And today finally I made my first 3 led clip. I had lots of problems with software but now it works quite good. I have tested it with WoP, LFS and FS9. Now I'm going to make new one clip with switch and led indicator ( to know if clip is on) because I always forget to turn off my clip. What I can say that it's MUCH funnier than just buying Track Ir. Good job guys.
