Here’s a posting from a new (happy!) customer originally on spyderlovers.com:
OEM Style Mirror Turn Signal® Lights
After all the looking at the LED Strips, Arrow stick-on, etc. I decided to spend some more hard earned money ($219.00 to be exact) on getting the first set of OEM factory style mirror turn signal lights from Muth Mirrors. Muth has an S-MOD program where you send them your mirrors and they will replace the mirrors with the factory style mirror with build in arrow lights. They complete the process and ship them back in 7-10 days. Mine took 6 business days to complete and 3 days each end for UPS shipping. Their box was better packed then the one I send them and everything is in perfect condition.
All I had to do is connect their wires using Posi-Tap connectors to the leads on the mirror and re-install the mirrors. Below are a couple of pictures showing the mirrors in the off and on position.
Here are a couple of links to their web site to check out the s-mod program and pricing.
