I have it installed on my GT along with hyperlites. It was very straight forward to install. The taillight is brighter than the hyperlites. Call this overkill, but after being rear ended at 45mph by a cage while stopped for a left turn on my RS (RIP), it makes me feel a bit better.sreynen said:Has anyone mounted a gizmo mill led taillight on their RS or GT? Ease of installation?
