Sindarin Translation for "A light from the shadows shall spring"

Been trying to find the most accurate translation of the quote "a light from the shadows shall spring".

Planning to get it tattooed. Any help would be incredible!!!

Thanks so much :)

If you're getting this quote tattooed, then I would recommend transcribing it into Tengwar (i.e. writing the English in Elvish script) rather than translating it to prevent the translation from becoming obsolete as more of Tolkien's linguistical work is published. A Tengwar transcription of the quote would look like this. If you'd like to change the font and stuff, you can head over to Tecendil (the site I linked) or Glaemscribe and play around with that.

If you don't mind the phrase potentially becoming obsolete and still would like a Sindarin translation, here's what I offer:

Calad uin gwaith eriatha (a light from the shadows will arise)

Calad uin gwaith echuiatha (a light from the shadows will awaken)
