(written from a Production point of view)
Polar Lights Models is a manufacturer that produces Star Trek model kits, starting in 2003, as then regular kit producer, AMT/Ertl, started to wane in their releases of its Star Trek-line. Currently featuring a substantial line for themselves, two releases in particular, the highly detailed 1:350 scale models of the original USS Enterprise and its refit successor, are highly acclaimed in the Star Trek modeling community.
Polar Lights Models was the model kit-making division of toy company Playing Mantis, set up in 1994 with the specific intention to re-issue Aurora Plastics Corporation's signature monster and science fiction kits of the 1960s and 1970s. The company's name itself was an homage to "Aurora" (both references to the northern and southern polar lights). Apart from the figurine kits, the company also produced scale models of famous vehicles from various TV and movie projects, such as the Ghostbusters ECTO-1 and the Back To The Future Delorean Time Machine.
Star Trek association
In 2003, Polar Lights started to release Star Trek model kits, including some not previously released designs, having been given the license as then owner of AMT/Ertl (hitherto the regular licensed manufacturer of Star Trek model kits), Racing Champions, showed no interest to develop the Star Trek model kit line any further. At that moment in time, no Star Trek model kits had been marketed for four years. Unfortunately, holding company Playing Mantis itself was acquired late 2004 by the same Racing Champions and production of new model kits was halted immediately by the new owner, resulting in 2006 in the announcement of Polar Lights' closure, due to the elimination of the brand. 
Still, one year later in 2007, the product line of Polar Lights was sold to Round 2 LLC, having also acquired AMT the same year, and the brand was revived in 2008, resulting in that all active US-based licensed Star Trek model kit manufacturers were once again united under one roof. In June 2009, Round 2 indicated that by 2010, they would start releasing entirely new models under the Polar Lights brand, starting with the alternate reality USS Enterprise from Star Trek and the USS Thunderchild from Star Trek: First Contact. However, these two have been canceled as of 2012.
