I used it in combination with the top view tape I purchased last time. Top viewing tape alone is sufficiently bright, but I also attached it to some somewhat tilted place with greed, so I think that it is easy to see from every angle.
I used it as daylight LED. It stuck to the edge of the headlight, but it can be pasted easily because bending works to some extent. Although it can not be helped structurally, since the place to paste is limited because it does not bend sideways, I would like to devise a little more ingenuity. I am satisfied that it is brighter than I expected.
