Toyota company offered all Toyota tundra buyers for free service of front lights that were faulty wired in the process of assembly. This offer is for buyers between Feb 2019 to 2020 and free of charge.
For this purpose, letters will be sent to affected owners only the lights are offered to be fixed but no other problems like brake fixing etc. dim front lights and turn signals seems like a small problem but as NHTSA notes dimly lighted turn signals are not recognized by oncoming traffic, and there might be greater chances of a collision. So it's better to resolve the problem rather than being a cause of big issues.
