Condensation does not affect the function or performance of the reversing lamp assembly. Refer to the Exterior Lighting Concern Analysis GSB (General Service Bulletin) to determine if replacement is recommended. If lamp condensation levels do not meet the GSB condensation lamp replacement criteria (lamp does not exhibit; non-impact related cracks/damage, water streaking down the inside of the lamp or water pooling on the inside bottom of the lamp) reversing lamp assembly replacement is not recommended. New reversing lamp assemblies are not expected to improve condensation performance over the original assemblies on vehicles that do not exhibit replacement criteria symptoms previously mentioned. Engineering is aware of this condition and is investigating a service solution which is expected to be available by October 2026. Schedule an appointment with the customer when the repair is made available.
