The LED strip I am using is 5mm (width) * 190mm (length). Any brands will do if they come in those size.
Below is a visual of where they sit (highlighted in blue). That is 4mm wide and I have to mill a 1mm deep pocket inside both blades to acheive that perfect fit. Bear in mind, the OEM deflector window is 4mm thick. I admit you have a great idea but it's not going to be easy - if you are to stick to OEM size anyway (i.e. reuse your porsche bracket).
EDIT: Tony, just an idea.... make your own custom PCB with some 3025 dual-color leds. Doesn't have to be a "flexible" strip of LED specifically. That would work mate. Talk to Charles for schematics if you aren't too electronic minded... he does that when he sleeps this guy
