Yes, a vent is required or the headlight would pressurise and explode as it warms up. Never seen a drain. On any car with HIDs, any water that gets into a headlight will end up in the HID control module, which is normally on the bottom of the headlight, and short it out. 30k Volts and water do not mix.
