Baja Designs part 660113 is a replacement lens for S2 light pods, supplied in green with a spot pattern. The manufacturer builds its uService line around swappable optics that seal with an O-ring instead of silicone, so you can change a damaged lens or switch beam patterns without buying a new light. The manufacturer describes green as a dust and marker light color used by certain race organizations, which makes this a practical choice for desert, rally, or race-support lighting.
Compared with leaving a cracked or clouded stock lens in place, this kit restores the optic and keeps the light's sealing intact. The O-ring is the critical component: the manufacturer states it provides the waterproof and dustproof seal that makes Baja Designs lights IP69K rated, so the seal should be replaced along with the lens. The manufacturer also states that lens replacement with this kit does not void the light's warranty. Search terms buyers often use include "S2 Sport green spot lens," "Baja Designs 660113 replacement lens," "S2 light pod O-ring swap," and "IP69K lens replacement." Fitment details vary across sources. The manufacturer says the kits are designed for the S2 Sport and S2 Pro auxiliary lights, but it also says red, blue, and green lenses should be used only on the S2 Sport. Confirm compatibility with the manufacturer before ordering for an S2 Pro.

The manufacturer states that the S2 series lens kit lets you replace an old or damaged lens without voiding the light's warranty.
The manufacturer lists one lens and one O-ring per kit. The O-ring provides the waterproof and dustproof seal that the manufacturer rates as IP69K, so reinstalling a properly seated O-ring is part of restoring that rating.
Per the manufacturer's lens change instructions for S2 lights, the job is a bezel-and-lens swap rather than a wiring task. Remove the bolts that hold the front bezel using a 2.5mm Allen key. Lift the old lens out and note how the lens and O-ring are oriented before you remove them. On S2 housings, the O-ring groove sits in the housing, so press the new O-ring firmly and evenly into that groove. Set the new lens in the same orientation as the original, then thread the screws back in and tighten them to 6.5 inch-pounds, as the manufacturer specifies for S2 lights. Avoid overtightening, and make sure the O-ring is not twisted or pinched, since a poor seal defeats the IP69K rating.
