An evaporating black hole in the presence of an extra spatial dimension would undergo an explosive phase of evaporation. We show that such an event, involving a primordial black hole, can produce a detectable, distinguishable electromagnetic pulse, signaling the existence of an extra dimension of size L{approx}10{sup -18}-10{sup -20} m. We derive a generic relationship between the Lorentz factor of a pulse-producing 'fireball' and the TeV energy scale. For an ordinary toroidally compactified extra dimension, transient radio-pulse searches probe the electroweak energy scale ({approx}0.1 TeV), enabling comparison with the Large Hadron Collider.
