a side videw mirror is a 2-way mirror. The reason for this is this: you would get a double reflection from the wide viewing angle if it was a normal mirror.
normal mirror: you are looking THRU a piece of glass looking at a reflective coating. this is to protect the reflective coating.your rear view mirror works this way, and when viewed from an angle, you will get a double reflection that is apparent especially at night. Another proof o this is they use this principle for the day/night mode swich on your mirror!
Another example.....go to your bathroom, place your fingernail so the tip is touching the mirror. it will look as is you are about 1/4 in away from the mirror. No matter what you do, it never looks like your are touching the mirror.
Now go to your side view mirror and do the same thing, and you will find that you can "touch" the mirror surface. Another proof of this is the fact that you can easly scrach the mirror surface on your side view mirrors.
Now that ive flogged the dead horse, on with the story.
so now you understand how the mirrors work and why....
all mirrors have to have a dar backing because the reflective surfaces are always transparent.....so the only diffrence between a 2-way mirror and a normal mirror, is that a normal mirror has a black paint on the back or some black backing.
Now since your side view irrors have the reflecive surface on the front, the only place they can put the black backing is on the BACKSIDE of the mirror. So most automotive mirrors have a black piece of plastic instad of a black coat of paint.
END RESULT: alll you have to do is drill thru the black plastic backin, and the led will shine thru!

By the way, if you are measuring a 10M ohm resistance, you aren't doing something right  Feel free to ask any questions if you are in doubt.
E=V=Volts
Look here: Ohm's Law
Some people use E rather than V

I'll have to look in to the reasoning behind E=V. I haven't heard that one before and I am an electrical engineering student.

Bah! You people, it doesn't matter. In physics voltage is called electro motive force in certain situations, its denoted with Emf where the E is actually a squigly E, so its the same thing V= Emf = squigly E

Yeah, I was just going to say that. I was looking through one of my old physics books and saw that E (electro-motive force) is the same as V. So unless you are a physicist.....call it V. Enough said
