is it possible to put the oem 03-05 side mirrors on my 02 escalade ext? does it fit perfectly in? is the install for the power on the led going to be easy?

JPCustoms makes replacement glass for the 02s that addes the LED turn signal. You just have to replace the glass and run 2 wires to the turn signal resistor. It's probably just cheaper to replace the glass.

I put these on my '02, I love them because they turn on when I am in reverse or have the brakes on. I have seen others than only come on when you turn. They're easy to install if you have some know-how.

Those are the same as the ones from JPCustoms :thumbsup:

is this easy to install? im not good at this kind of stuff.
does the mirror replace the old one or is it attached to the old one?

Do these new mirrors still have the functions like the OEM ones such as the heated feature and the dim feature? Thanks!
