I just had a LED Tail/Brake light put on by HEP. The new light is about the same size width wise but about a 1/3 of its depth. Its tucked up and out of the way for when you lose your wheelie. Its got quick disconnects just like the stock one so if you need to pull it off for racing you can. This thing is bright to!!

He also makes some cool other gaurds for the Z400.
