This is the optional Traxxas TRX-4 Ford Bronco LED Light Set WITHOUT the Power Supply (TRA8026 - sold separately). This TRX-4 Bronco LED Light Kit uses the same TRA8028 Power Module as other TRX-4 light kits. This TRA8036 LED Light Kit provides a cost-effective solution to add lights to the TRX-4 Bronco by reusing the power module from previous installations. NOTE: Requires the TRA8028 Power Supply - not included.
