A lens for a trailer light includes a body that transmits light when exposed to light, and a pad operable to mount the lens in front of a light emitting device. The body has a first edge and a second edge located opposite the first edge. The pad is configured to position the body away from the light emitting device such that, when the lens is mounted in front of the light emitting device, a passage is formed between the light emitting device and the body. The passage that is formed has a first opening defined by the first edge of the body, and a second opening defined by the second edge of the body. The first and second openings are configured such that water enters the passage when the lens is mounted to the light emitting device and the lens and light emitting device are submerged in water, and the passage does not hold water when the lens and light emitting device emerge from being submerged in water.
