Whats the point of having strobes on during daylight anyway?
If you want to attract attention, you have to have a contrast - if its dark,flash a light; if its quiet, make a noise; if its light, make a shadow.
Flashing a light against a light background has little effect. I can more or less garantee that the next light aircraft that you see in flight, you will be attracted to it by the engine noise, you'll see the dark silhouette next and finally you'll notice its strobes.
