>As they can be a little fragile, and frankly it's just wasting a tiny bit of fuel, no I don't use it all the time as a conspicuity aid - that's what strobes are for.<
Strobes on most civilian light aircraft seem to be fairly ineffective in normal daylight as conspicuity aids because of their low intensity. In my experience students usually see landing lights before they see strobes, as do I. Even the HISLs on our local military helicopters don't show up that well in bright daylight.
