There is no danger of dazzling anyone, but there is a danger of the light breaking up your visible silhouette, thus depriving the observers brain of the visual datum required to accurately calculate your speed - this makes T bone type scenarios much more likely. This was discovered in the 80's by Suzuki. The matter was further researched by Honda, who at the time owned a major searchlight manufacturer so had world class optics expertise to call upon, and they discovered the same phenomenon. And having discovered this the EU ignore it completely and also mandate DRL set ups for motorbikes.
The safest day time set up for a 2 wheeler is 3 low output lights arranged in a triangle, such as BMW fit to some models. In the event that your visual signature is obscured the observer can still calculate speed by the rate at which the triangle 'grows' as it approaches. Simply slapping a regular bright bike light in the middle of your bars serves only to potentially mitigate one risk at the expense of exposing you to a different one.
Next time you're riding towards a motorbike running lights during the day you'll see this phenomenon for yourself if you're paying attention.
Every action has a consequence, even things supposedly done in the name of safety. Slapping up daytime lights and blithely thinking it makes you safer actually makes you more likely to get yourself into trouble - think about the downsides as well.
