The word(s) "light" appears 125 time(s) in 114 verse(s) in Quran in Muhammad Pickthal translation.

(41) He it is Who showeth you the lightning, a fear and a hope, and raiseth the heavy clouds.

(42) Say (O Muhammad): Who is Lord of the heavens and the earth? Say: Allah. Say: Take ye then (others) beside Him for protectors, which, even for themselves, have neither benefit nor hurt? Say: Is the blind man equal to the seer, or is darkness equal to light? Or assign they unto Allah partners who created the like of His creation so that the creation (which they made and His creation) seemed alike to them? Say: Allah is the Creator of all things, and He is the One, the Almighty.

(43) Alif. Lam. Ra. (This is) a Scripture which We have revealed unto thee (Muhammad) that thereby thou mayst bring forth mankind from darkness unto light, by the permission of their Lord, unto the path of the Mighty, the Owner of Praise,

(44) We verily sent Moses with Our revelations, saying: Bring thy people forth from darkness unto light. And remind them of the days of Allah. Lo! therein are revelations for each steadfast, thankful (heart).

(45) And Allah hath given you in your houses an abode, and hath given you (also), of the hides of cattle, houses which ye find light (to carry) on the day of migration and on the day of pitching camp; and of their wool and their fur and their hair, caparison and comfort for a while.

(46) And when those who did wrong behold the doom, it will not be made light for them, nor will they be reprieved.

(47) Or feel ye secure that He will not return you to that (plight) a second time, and send against you a hurricane of wind and drown you for your thanklessness, and then ye will not find therein that ye have any avenger against Us?

(48) When the young men fled for refuge to the Cave and said: Our Lord! Give us mercy from Thy presence, and shape for us right conduct in our plight.

(49) And when ye withdraw from them and that which they worship except Allah, then seek refuge in the Cave; your Lord will spread for you of His mercy and will prepare for you a pillow in your plight.

(50) And thou wouldst have deemed them waking though they were asleep, and We caused them to turn over to the right and the left, and their dog stretching out his paws on the threshold. If thou hadst observed them closely thou hadst assuredly turned away from them in flight, and hadst been filled with awe of them.
