 Black lights can be spotted by the illumination they emit in dark areas, especially if the light seems to come from nowhere. They are most easily dealt with by [[blind]]ing yourself using a [[blindfold]] or [[towel]] and waiting for it to explode harmlessly at you, then remove the blindfold or towel after. You can also take the brunt of the explosion and apply an immediate cure, such as a [[unicorn horn]] - though a [[potion of full healing]] can also cure hallucination, this is best saved for more dire scenarios. Wielding [[Grayswandir]] if you have the [[artifact weapon]] provides [[hallucination resistance]], but does not cure the status and only suppresses its effects.
-Try to avoid leaving strong [[pet]]s near black lights, since they may turn on you in their confusion and [[YASD|batter you to death]]; this can also happen if you have [[displacement]] and the black light targets a displaced image on your pet's square. Monsters have a {{frac|50}} chance of recovering from confusion on each of their moves{{refsrc|src/monmove.c|414|version=NetHack 3.6.7}} - intelligent pets will cure their confusion using a unicorn horn, making it vital that you equip them with spare ones as soon as possible.

 Once you have the see invisible property, you can reliably detect and intercept black lights before they explode; [[warning]] can also hint at the presence of a black light as well. As with yellow lights, though it is possible to kill black lights if you can deal with their 0 AC and fast, erratic movement, it is usually quicker to let them explode at you while blinded. Beware of possible black lights anywhere near [[treasure zoo]]s such as the one in [[Sokoban]] and other monster-filled [[special room]]s.
