Replace or upgrade the OBS side markers on your 1988-1998 Chevrolet or GMC truck with a set of side marker lights from Truck Resto! Side marker lights are on the outside corners of your grille and provide extra illumination at night. Over time, these lights oxidize and become faded. Now you can replace them with your choice of factory replacements, or aftermarket clear side markers! Shop our selection of OBS side marker lights below.
