I think the water ingress issue is exacerbated because the plastic angled plinth (6 below) does not provide a a smooth flat surface for the lamp and particularly it's rubber backing to sit against, allowing it to pucker up when bolted up tight to inner wing. This because of the moulded internal bracing of same. Plenty of silicone grease on assembly should prevent water ingress though.

Although not shown there should be a very short length of steeply angled snug fitting rubber tube (to match slope of inner wing) added before washer and securing nut are also added. When tightened this should stop water creeping up securing bolt threads.
