Has anybody been able to access the third brake light? I would like to add one of those strobe brake light modules like this one https://www.amazon.com/dp/B0185HMIIQ/_encoding=UTF8?coliid=I1A2X5F1JN7U5A&colid=1S71XZJ5WDXOL to it and I can't figure out how to access it. Any help would be appreciated.
