These LED side marker lights by Recon are a direct plug-n-play replacement for factory installed lamps that come as standard equipment. However, even if your vehicle was not equipped with factory side marker lights, these lights will also look great on your truck with some minor drilling and wiring required. Whether you drive a standard/regular cab, extended cab, quad/crew cab, or dually, Recon has the right LED side marker lights for your rig. Specifically designed for turbo diesel dually trucks, this kit is easy to install on just about any four-wheeler with some modifications required. The kit is street legal and is build to meet or exceed strict industry standards and requirements. The lights come with ultra-bright LED bulbs, which provide increased light output to ensure maximum visibility in harsh weather conditions and at night. Together with high-grade lenses, the bulbs give a vehicle a one-of-a-kind appearance to make your vehicle stand out from the rest.
