Dua E Noor

Not sure which du'a you are reading, but this is what is mentioned in a couple of saheeh ahadeeth (the words of the du'a being in red):

حَدَّثَنَا وَاصِلُ بْنُ عَبْدِ الأَعْلَى، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنْ حُصَيْنِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ حَبِيبِ بْنِ أَبِي ثَابِتٍ، عَنْ مُحَمَّدِ بْنِ عَلِيِّ بْنِ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، أَنَّهُ رَقَدَ عِنْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَاسْتَيْقَظَ فَتَسَوَّكَ وَتَوَضَّأَ وَهُوَ يَقُولُ ‏{‏ إِنَّ فِي خَلْقِ السَّمَوَاتِ وَالأَرْضِ وَاخْتِلاَفِ اللَّيْلِ وَالنَّهَارِ لآيَاتٍ لأُولِي الأَلْبَابِ‏}‏ فَقَرَأَ هَؤُلاَءِ الآيَاتِ حَتَّى خَتَمَ السُّورَةَ ثُمَّ قَامَ فَصَلَّى رَكْعَتَيْنِ فَأَطَالَ فِيهِمَا الْقِيَامَ وَالرُّكُوعَ وَالسُّجُودَ ثُمَّ انْصَرَفَ فَنَامَ حَتَّى نَفَخَ ثُمَّ فَعَلَ ذَلِكَ ثَلاَثَ مَرَّاتٍ سِتَّ رَكَعَاتٍ كُلَّ ذَلِكَ يَسْتَاكُ وَيَتَوَضَّأُ وَيَقْرَأُ هَؤُلاَءِ الآيَاتِ ثُمَّ أَوْتَرَ بِثَلاَثٍ فَأَذَّنَ الْمُؤَذِّنُ فَخَرَجَ إِلَى الصَّلاَةِ وَهُوَ يَقُولُ ‏"‏ اللَّهُمَّ اجْعَلْ فِي قَلْبِي نُورًا وَفِي لِسَانِي نُورًا وَاجْعَلْ فِي سَمْعِي نُورًا وَاجْعَلْ فِي بَصَرِي نُورًا وَاجْعَلْ مِنْ خَلْفِي نُورًا وَمِنْ أَمَامِي نُورًا وَاجْعَلْ مِنْ فَوْقِي نُورًا وَمِنْ تَحْتِي نُورًا ‏.‏ اللَّهُمَّ أَعْطِنِي نُورًا

'Abdullah b. 'Abbas reported:
He spent (one night) in the house of the Messenger of Allah . He (the Holy Prophet) got up, brushed his teeth and performed ablution and said:" In the creation of the heavens and the earth, and the alternation of the night and the day, there are indeed signs for people of understanding" (al-Qur'an, iii. 190), to the end of the Surah. He then stood up and prayed two rak'ahs, standing, bowing and prostrating himself at length in them. Then he finished, went to sleep and snored. He did that three times, six rak'ahs altogether, each time cleaning his teeth, performing ablution, and reciting these verses. Then he observed three rak'ahs of Witr. The Mu'adhdhin then pronounced the Adhan and he went out for prayer and was saying,:" O Allah, place light in my heart, light in my tongue, place light in my hearing, place light in my eyesight, place light behind me, and light in front of me, and place light above me, and light below me. O Allah! grant me light."

Abd Allah b. 'Abbas said that he slept in the house of the Prophet . He saw that he (the Prophet) awoke, used tooth-stick, performed ablution, and recited:
"In the creation of the heavens and earth" [3:190] to the end of the surah. Then he stood up and prayed two rak'ahs in which he prolonged the standing, bowing, and prostrations. He then turned away and slept till he bagan to snore. This he did three times. This made six rak'ahs in all. He would use tooth-stick, then perform ablution, and recite those verses. He then observed the witr prayer. The version of 'Uthman has: with three rak'ahs. The mu'adhdhin then came to him and he went out for prayer. The version of Ibn 'Isa adds: He then observed witr prayer ; then Bilal came to him and called him for prayer when the dawn broke. He then prayed the two rak'ahs of the dawn prayer. He then went out for prayer. Then both the narrators were agreed: He began to supplicate saying: O Allah, place light in my heart, light in my tongue, light in my hearing, light in my eyesight, light on my right hand, light on my left hand, light in front of me, light behind me, light below me, O Allah, give me abundant light.

There is also a slightly different version in Sahih Muslim here: http://www.sunnah.com/muslim/6/225

In the du'a book, Hisnul Muslim (Fortress of the Muslim or Fortification of the Muslim), it is mentioned under the heading, "Going to the mosque".

There may also be other versions, Allahu a'lam.
