The strips of LEDs i can only cut to a length of 50mm which only comes out with 3 LEDs with one 150ohm resistor on it. on each strip has the negative & positive on both ends , i had to joint another strip of LEDs above to give a total of 6 LEDs. but that all i can fit in there , it's a tight fit.:mrgreen: The sets of reflector strip are printed out on 180g matte photo paper but i had to double the parts of the reflector to be glued on both sides of each 25 reflector. Here are the first two engine parts i have edit for the engine glow.
