Even if it is 100mA of total current (and this is a lot) the dissipation would be 2.5W. Nothing to sneeze at but 7.5W resistor will take it well.
My rule of a thumb: Rating is 3x dissipation.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
