Expect an even bigger drop in visibility from a white LED light in the wet. I'm not saying you won't find a LED light that ends up better than the halogen, but it will need to be much brighter to start with to be a little brighter in the wet stuff. Wet pavement just really kills the narrow bluish spectrum that LED headlights put out.
I've wondered how Dinotte's orange daytime light would perform in the rain.
How many lumens, watts or whatever of LED you need to equal or best a 15 watt halogen under different conditions, I have no idea.
