LED Tail Light Upgrade
Swapping out the tail light on the R100GS for an LED version eliminated having to replace bulbs a couple times a year and got me a brighter light to boot, so I was game for making the same upgrade on this R100RT. Unfortunately, GizmoLabs is no more, so I turned to Motorrad Elektrik and their Beacon II LED replacement.
Like the GizmoLab product, this one relies on individual LEDs on an encapsulated circuit board, sized to closely fit the contours of the '79 - '95 BMW street bikes. Red LEDs dot the back of the board, while a row of white LEDs provide license plate illumination on the other side.
