Daytime safety is harder to enhance but can be done. A bright white strobe on the front of the bike and a bright amber flasher on the rear should help. Still, I consider the best thing to do for increased visibility in the day is to wear a bright yellow jersey or jacket. When ever I'm behind the wheel the first thing I notice when I see a cyclist during the day is "what they are wearing". ( few people use lights during the day, I personally am an exception to that rule ) The yellow jerseys always stick out like a sore thumb. I never ride daytime on the road without one.
Most of us here know exactly what you are referring to, but in the case that newbie or someone not quite so familiar stumbles upon this thread, I'd like to point out that, while yellow colored cycling clothing help; the "better", more visible color is chartreuse. One can purchase vests/jackets/etc. in yellow, however for greater visibility, if that is your goal, opt for a chartreuse colored vest/jacket instead.
