First off, I'd like to say thanks to XtraLargeTall for inspiring and answering some questions about this little project. He installed his lights last year but I've wanted to add them since I bought the truck in May of 2012.
I used a slightly different light than XLT used. I ordered the lights from Custom Dynamics. http://www.customdynamics.com/trufle...d_lighting.htm
I used one 10 LED strip for each mirror. These lights measure 2.17" long by .25" wide by .30" tall. I'm using the amber LEDs with the smoke housing. I also ordered one 2 to 3 wire converter for each mirror. This lets the LEDs function as both running lights and bright turn signals.
I found it much easier to remove the whole mirror assembly from the truck before doing any work to it. I found that removing the mirror glass and splitting apart the mirror housing to be a royal pain but neccessary to be able run the wires how I wanted.
The key with this project is take your time and don't use too much force. I didn't break a mirror but I broke 4 clips in each mirror that help hold it together. The clips were only on the telescopic arms anyway so I just used some hot-glue in each spot when I re-assembled the mirrors.
Here's the finished product:
I wanted to take more pics but as I started running out of time, I was sort of rushing just to get it done.
