Hey, I just noticed that the passenger side rail light on my 2019 F150 w/BLIS LED tail lights only has the ring and the top light working. The drive side has the ring, top, and bottom are all working. Doesn’t appear to have “bulbs” to replace. What does a guy do? Thanks!

 

If the wiring is okay and you are getting voltage to the correct pin on the taillamp assembly, then get out your wallet! You have to replace the taillamp assembly. You do not need to buy a new SOD (Side Object Detection) module (aka: BLIS module) if the old one is still working. It can be transferred over to the new taillamp.
