First off, welcome to IRV2!
The headlight assemblies are normally OEM equipment from some car or truck. If you look closely at the bottom of the clear front, there will be a series of numbers that are the DOT designation for that headlight. You can do an internet search for the number to find out what they were originally used for. For example, the ones on our 2015 Allegro RED were from 2004-2007 Chevy Silverado Pickups but they are different from yours. If yours are clouded up, then replacement with Silver Star bulbs might be in order.
