This rectangular LED Marker Lamp is the solution for those who need to run a combination marker lamp and turn signal in the same unit. This may be necessary on Jeeps where the OE turn signals and/or marker lamps were removed in order to install aftermarket armored fenders such as Poison Spyder DeFenders. Unlike our 3/4" Round LED Marker Lamp, these are a 3-wire lamp which can perform two separate functions (minor and major-or typically, marker lamp and turn signal).
