A flashlight works really well and won't require all the horsing around that others have suggested. If the aircraft did not come from the factory with the ice light it's going to take a field approval. It can be done but can be frustrating and there is no guarentee that the local FISDO will approve it. .

I have two types of flashlights in the cabin. Incandescent for straight pin point beam and a LED for a bright flood. I actually like the flashlight method a lot better because I can look at the wing, the strut, the landing gear or any other part within a reasonable distance. Several flashlights in the cabin are not a bad idea anyway.

Keep it simple, stay safe.
