Recon's Warranty: Recon offers a 90-Day Limited Warranty for manufacturing defects, including condensation. These lights do have a breather vent that allows for pressure changes, which can trap some amount of moisture and cause condensation problems. Condensation issues will not be covered outside of Recon's 90-Day Warranty period. Feel free to call Stage 3 directly at 623-434-5277 with any questions or concerns.
