Help! RC4WD LED control unit

[Badboy_207]

Hi!

I got:
Scale Lighting System (Ver 2)
And I can't use it in my Trailfinder 2 as the LED are to big!
Can I just remove the 5mm and replace them with 3mm?
The only 5mm I need is for the front (head-) lights, the rest are supossed to be in 3mm... Can I ad two 3mm for one 5mm? How does this work?

Thanks for any help!
