Irish lights?

Irish lights?!?!

There is only one type of Irish light.

Intermittent.

Come to think about it, there may be a few more after all.

Subdued. Asphyxiated. Burgeoning. Perishing. Flickering. Struggling. Emaciated. Suffocating. Under-achieving. Disappearing. Depreciated. Diffused. Confused.

Shy. Inexistent.

Dying.

Dead
