Well, I think that the word flashlight has no Filipino translation. But here is some things that I think is the Filipino word for flashlight:
Lente - Lens
I recommend you to pick on the last three, or pick the word plaslayt for it to be more appropriate.
Pansit or Pancit, in English I think is noodles. But the english term for it (I guess it is also Chinese term) is pancit because the Chinese introduced noodles to us.
