The listing is for (1 pair) of Orange marker lights. All connections are soldered and heavy duty adhesive lined heat-shrink tubing is used where the wire enters/exits the marker. Includes 3 feet of stranded copper wire for each marker guide. These only draw 1.4 amps each so in most cases they can be tied into existing lighting circuits. They have 3/8″ holes 1″ on center.
