I ordered led turn signals for the mirrors.
I'm not the 'hey look at me on my bike' guy at all...but I do like the lights to be noticed by idiot drivers, so leds are always an improvement.
$40, plug and play, with some good youtube reviews, so I'll give them a try.

My GW came with these air deflectors on the mirrors($70) and I was amazed at how well they work.
I had them turned flat to the front/closed when I got the bike, and then realized how hot my hands were, even with my well vented summer gloves.
I then turned them fully open, and wow, direct airflow on my hands, and they were instantly cooler.
These are an impressive any season mod, that really works, and isn't that expensive.
The bike came with them on the crash bars for your feet too, but one was broken, so I'm going to repair or replace it and try it when it cools down outside.
Just an FYI on something that would be really good touring, without breaking the bank(if you don't already have them).
