Nah usually the tops of the lights cop all the sun and the seals just deteriorate over time, no holes for drainage as they aren't supposed to leak, once the water is drained the heat from the sun/globes will dry them pretty quick. I think I used a 2mm drill bit or whatever was the smallest I could fit in the drill.............Just don't try to drill through glass but yours should all be plastic, if not hit the backing plates.
