As you might be aware, all 9-4X tail lights fail, this is due to flexing of the board and connectors. We’ve made a new circuit board with strong connections and no flex-band. Leds are current controlled as we usually do and this board has been tested in -200degC conditions, and the original circuit board fails even above 0degC.

This kit is in the black-series with coating on the circuit boards!

These are only sold in pairs!
