I think the HS2 light is too tall. There has been a lot of interest in doing this but so far nothing to show. The original stop light is quite deep to accommodate the length of a 44/47 bulb. With the new LED's available, specifically the typical "super-brights" that do not have a dome on the bulb, the body could be redesigned perhaps more like what a real stop light looks like. Probably a good candidate for a 3D print.
