thanks for the inspiration!
I didn't do a write up, because I'm counting on Dammitboy, that he will do it and besides I'm lacking the technical knowledge. I just went to the nearest electronic store. talked to the salesman, what I was going to build and asked him for a bit help and I got the right parts. I installed 117 red LED's in 39 groups. 3 LED's in each group with a resistor and I installed all the 39 groups parallel (i don't know if that's the right word in english) and I was done. if you don't have that helpful salespersons and you know the specifications of the LED's then you can also use this website:

now i'm going to start with the tail lights centre part (reverse lights) and then going to finish off the sides of tail lights. this has been a very interesting project!
