In this video, we install the next mod for my 2019 Harley Davidson Street Bob. I got a set of the Kuryakyn tracer diffused rear taillight inserts (red lens). This upgrades the bike from the factory bulbs to LEDs which are much brighter and look way better. Unfortunately the GoPro I use to film does not really pick up how they look, but you can get a feel for the brightness difference based on the video.
