This should take you about 5 - 10 minutes to do the swap.
if you get the strips like so http://www.oznium.com/led-flex-strips they are 12V ready so you can just splice the wires into the two factory wires and they don't require a resistor or anything.are the LED's in the mirrors plug and play? or do you have to add a load resistor like for the main turn signals?
Where did you get these clear lenses to be able to swap them from! and how much $$$$!
