I have a single pannier and always keep in on the right. At night, it allows cars to see my left pedal reflector (yes, I have pedal reflectors) and sometimes I use a reflective ankle strap on the left, too. Reflectives that move are much more attention-getting to cars than others.
Sounds like you would not have reflectors on your clipless pedals though!

In that case, you might think about putting a strip of white reflective material on your crank arm facing front and/or back. The white material is almost invisible during the day, but the motion makes it pretty visible at night. It's easy to remove later, too, without leaving any trace.

I'm riding a single speed, so off the line is a bit tough, and about 2 miles in, the back wheel fell off as I jumped the light. I was also having some trouble with the rim rubbing the brake pad. I guess it rides a bit different with no load than with a load.
Should my bag be on the left or right side of the bike? I only have one saddle bag and a trunk bag.
