snow covered tail lights

I have a 2012 SR5. When the roads are snow covered, especially when it is billowing behind the truck, the snow sticks to the tail light covers and after a short time driving the entire tail light is completely covered in snow, along with the rest of the back of the truck. This is really bad when driving at night - no tail lights in effect. These are LED tail lights so there's no heat to melt the snow.

Are there any fixes for this? ie. non-led bulb replacement? Some kind of heater to plug in?

Thanks
