running them under the door rather than the wing mirrors means they would only be 50% effective. puddle lights by their definition are designed to light the area
outside the car.
Being on the mirrors, coming to the car or getting out of, the lights flood the ground. if they were under the doors then they would only be effective when you get out of the car and not as you approach it to get in.
for that reason it would be OEM mirrors with LED's or nuthin for me
when i ordered my car i decided i wouldn't need them, now i want them because i haven't got them. In a year or so I will be selling the mrs's EOS and that has got them, wing mirror swap and all's good
