For those who are using the Optronics driving lights (QH-7CC, chrome version), is it necessary to take steps to waterproof them? There's a hole at the rear where the wires exit and a small gap between the bulb's glass cover and the bezel. It seems to me that, without any further steps (e.g., a drain hole in the bottom or sealing the holes, the light would accumulate water as I ride through the rain (or leave the bike parked in the rain).
