Although it might be headed to extinction, the Ford Ranger is the subject of one more recall.

With less than half a year left in its lengthy production cycle, you'd think it would be smooth sailing for Ford's St. Paul, Minnesota-built Ranger pickup.

That's apparently not quite the case, since Ford has been forced to recall around 20,450 Ranger pickups to replace a defective switch that could prevent turn signals, hazard lamps, tail lamps and brake lights from working.

As a result, the National Highway Traffic Safety Administration says that the Rangers post an increased risk of being involved in an accident - not to mention that they don't pass federal safety standards without the necessary lamps.

The recall affects Rangers built between January 25 and April 25, although some defective items might also have been installed on other vehicles as replacement parts. Ford says that the switch was used in 2004 to 2011 Rangers, 2002 to 2005 Excursions and 2002 through 2007 F-Series pickups. Ford dealers would have had to replace light switches in those vehicles.

Ford and NHTSA say that the recall will commence in mid-August when it will instruct dealers to replace the faulty switch. Concerned owners are directed to contact their dealers.
