I'd be interested to see this entire bike instead of just parts of it. Depending on what bags you are running in the rear your rack mount may or may not tend to get in the way. A Portland Design Fenderbot would be a something to consider for the rear.

Is there a reason why you're not running your front light off the handlebars? I personally do not because I use a handlebar bag. In my case I go with a fork mount.
