context_page_description: Blackout lights are head and tail lamps that are equipped with special lenses that are designed to cast a diffused horizontal beam of light for the driver of the vehicle to navigate with, and drivers of other vehicles to spot the vehicle with. In the military, they are intended for use when driving a convoy at night when it is necessary for the vehicles to maintain concealment by limiting their ability to be seen by the enemy.
context_section_description: Front marker lights are typically mounted below or to the side of the vehicles normal headlights.  They serve the purpose of making the vehicle visible to oncoming drivers or for a driver to see if a vehicle is following him or her.
  Rear marker lights or blackout taillights are typically housed in the same unit as the vehicles taillights, and are the main tool in keeping the proper following distance in nighttime convoy driving.
  Blackout Marker Lights serve the purpose of marking the position of the vehicle during blackout driving. They also are used as an aid in keeping the proper safe following distance when driving in a convoy at night. US Military marker lights are designed with a series of "cat eyes" that appear differently depending on the distance one is away from the vehicle that is equipped with the lights. When the following distance is too far the rear marker lights appear as a single red light and when too close as four separate red lights. When the correct following distance of 180 to 60 feet is maintained the taillights appear as two red lights.
