Part 660131 is a Spot-pattern, Factory Amber replacement lens for Baja Designs S2 light pods, supplied as one lens with one O-ring seal. The manufacturer's S2 lens family offers four patterns: Spot, Driving/Combo, Wide Cornering, and Work/Scene. Because the optic can be swapped, a cracked or scratched lens can be fixed without replacing the whole light. The factory amber option is intended to match the OEM running lights on today's vehicles, which helps the pods blend with the factory look when used in fog, dust, rain, or snow. Those are the conditions where a warmer, less intense beam cuts glare.
Fitment is the key buying question. These lens kits are designed to fit the S2 Sport and S2 Pro auxiliary lights. The swap is a practical DIY job. The manufacturer's uService instructions call for a 2.5mm Allen key and list a torque value of 6.5 inch-pounds for the S2. Owners report quick work: one reviewer said 5 minutes for 2 lights. Searchers looking for an S2 Sport spot lens, an S2 Pro factory amber lens, or a light pod lens swap will find this kit matches those needs.
The manufacturer states that the S2 lens kits are designed for the S2 Sport and S2 Pro auxiliary lights.
The manufacturer states that the S2 series lens kit lets you replace a damaged lens without voiding the light's warranty.
The manufacturer notes that assembling the lens incorrectly can leave the customer responsible for repair costs if the installation is found to have caused damage.
The manufacturer's instructions describe a straightforward bench-or-driveway swap with a 2.5mm Allen key and 6.5 inch-pounds of torque on the S2. Before removing the old lens, note its orientation, since the replacement must go back the same way. On S2 pods, the O-ring groove is in the housing, so press the new O-ring firmly and evenly into the groove before setting the lens. The manufacturer recommends installing the screws only partway at first, until every screw is in place, then tightening to spec. Take care with the seal: a poorly seated O-ring can compromise the dust and water protection.
