Ha, i was thinking about this today driving behind some crap looking european car with LED tail lights. I reckon it would be mad. Prob wouldnt be hard to use original shaped parts. Just wondering if the ampage etc might be different as they don't need as much power. Relays. Etc etc.
I was also thinking those LED running lights, then went, ummmm na.
And if ya need arrows to know which way a car is going it must be American :)
