The rear status led on the Latrax Alias is blinding at times. So I came up with a diffuser to alleviate this and increase visibility. v2 has curved bottom to improve visibility. Print with zero infill to keep it light weight. I'd recommend some paint inside the tip of the led hole to cut down the glare, it really is that bright, which is what I used. It fits tight on the led, I highly recommend some removable adhesive that would help keep it on in a crash. Do not use too much force when installing it. You are pushing on the led tabs and board mount. The led is installed on the frame with an o-ring. Mounted easily attached to the same screw points that hold the body on.
