The 3D printed gasket opens up a world of fender/side lamps to you and that particular one looks nice.
One of the advantages to a fender lamp for short people like myself is that from a normal seated position I can see the top (about 50%) of the fender lamp letting me know where the fender really is located. Seeing that glowing fin is pretty cool and I will get a video of it the next time I am out at night.
