I wanted to do something similar to the JDM style mirrors but don't really care for how big that light assembly is in comparison to the rest of the mirror covers. So, I instead went on an odyssey to try to do my own thing. What got me thinking about this in the first place was the large amount of space between the outermost edge of the mirror and that edge of the mirror housing / cover. The video below shows the end result after trying 5 different LED options. I will post more details and pics of how I drilled the holes into the mirror housing and the LEDs used. I have also installed puddle lights but do not have them connected to the interior dome light just yet. I will post pics & a video when I get them connected. BTW, all of the turn signals are LEDs and you can get an idea of how bright the ones in front are by the illumination of the driveway.
