I feel like there must be better options than resistive heating to melt the snow.
For example instead of a separate visor for each light, use a single visor that covers all three lights. And maybe angle the whole thing forwards slightly so that there isn't even a vertical surface for snow to rest on - gravity would simply cause it to fall off.
