I thought I would pass on another weeze I have picked up in ten years of owning a lexus LS400. The parking lights on my car filled with rainwater because my drive had an incline causing the water running off the bonnet to drip back onto the top of the parking light and somehow enter the plastic enclosure.although this did not cause any electrical problems it looked unsightly and mist formed on the insideof the lens. Solution! needle drill the bottom end of the enclosure as near to the lens as possible and the water will drain away,every time.Use the tutorial for changing the bulbs to remove the enclosure.

good advice......
