Is the LVQ-212 water and acid proof?
No. It is designed to withstand light mist of non acid water. Splashes from high pressure washers, big pot holes, heavy downpour with hood open, garden hoses, liquid battery acid and battery fumes will enter the ballast unless protected. In most cases electronic components that are build in will degrade and ballast will intermittant or permanently fail. If water enters ballast overtime, it will create corrosion and eventually a total failure will happen.
