Replaced the stock third brake light on my ‘19 with the OEM LED third brake light from the ‘21+’s (Part # 68444540AB). A bit overpriced for what it is… but after seeing some of the quality control issues on the aftermarket ones, I decided to splurge and get the OEM CHMSL. The cargo light is mediocre compared to the
JDM ASTAR LED’s I had in the stock housing, but I have plenty of bed lighting to make up for it, so it’s not a big deal to me. The brake light, however, is incredibly bright - like laser beam, blindingly bright when directly behind it. I was concerned about how the housing would seal against the cab since it only mounts with the 2 outer screws instead of all 4, but it uses clips to replace the 2 inner screws and actually seals up tighter than the stock housing. Overall, I’m pretty happy with the look. I think it’s a great match with my DIY Night Edition LED tail lights.
For anyone wondering, the camera in the housing is for the digital rearview mirrors found on the ‘21+’s. As of now, the digital rearview mirror cannot be properly retrofitted to the ‘19-20’s due to BCM limitations, but I have seen other members working on possible solutions for this, including replacing the BCM with a ‘21+.
