• see the light

• make light of

• give the lie to it

• be all sweetness and light

light-fingered

• as quick as lightning

• according to one's lights

• go out like a light

• daylight robbery

• many hands make light work

• in the cold light of day

• come to light

• do a moonlight flit

lightning never strikes in the same place twice

• like greased streak of lightning

• a flight of fancy

• in the light of it

• not in the slightest

• knock the living daylights out of him

• in broad daylight

• in the limelight

• bring to light

• see daylight

light years ahead

• hide one's light under a bushel

• make light of it

• a leading light

• top-flight

• beat the living daylights out of him

• the green light

• shed light on it
