This is yet another taillamp with crap optics, far too high light density because of a near-point-source of light. I have described this problem in many reviews of taillamps, so briefly: This annoys and even blinds at close distance (depending on surrounding light etc.), it makes distance estimation impossible.

This alone makes any further examination of the brakelamp functionality pointless. This is a poor lamp, avoid!

Beam shots

See the camera settings page for more on the setup and settings to make pictures of the beams of taillamps.

From 2014 on I will not make beamshots of any further taillamps with poor optics, it's just a waste of time! So, no beam shot pictures of this taillamp.
