(AP) - Government safety regulators have closed an investigation into headlights that can go dark on older Chrysler minivans.
The U.S. National Highway Traffic Safety Administration says Chrysler is offering a lifetime guarantee on the headlight switches, and that will take care of the problem.
The government began investigating 2005 and early 2006 Chrysler Town and Country and Dodge Caravan minivans in 2011 after getting complaints about headlights failing.
More than 620,000 vans could have the problem. It was traced to bits of plastic getting caught in headlight switches. The problem worsens as the vehicles get older, and can be fixed by turning the headlights on and off.
The government says Chrysler is offering a lifetime warranty on the switches and will replace them for free when people start to have problems.
