What exaclty does the leglisation say about reflective gear?
Nothing. There is no legal requirement to wear hi-vis clothing or a helmet when cycling in Ireland, or in the UK.
That didn't stop the UK police responding to the recent spate of cyclists killed by other vehicles with a bout of 'victim blaming' - stopping and 'advising' cyclists to wear helmets and hi-vis.

They wouldn't get away with victim blaming with other types of crime. I'm not sure why it is acceptable in the case of cyclist deaths.
