Just adding the chip just makes it digital compatible. I have no idea on light boards, never researched that far.
I think the lights are ok, bright enough for me. No, not working brake lights.
If you want better lights then after-market kits or home built are always better. In fact, Jeremy (bibbster) makes his own kit and he is converting a car for me. And much cheaper than some of pre-made kits.
And since he is doing that, I likely won't bother going the digital route anymore just for them.
So looks like I will have a few digital boards to part with soon.
