What's wrong, in plain English
Toyota is recalling certain Tundra trucks equipped with LED headlight assemblies. Because of a wiring error, the front turn signals may not flash brightly enough. This means the turn signal and hazard lights might not be as visible to other drivers as they should be. Dealers will fix the wire harness connected to the front turn signal bulbs to correct the problem, at no cost to owners.
