A side effect of cold LED headlights, they don't defrost themselves. Having a layer of frost makes them really ineffective and they are hard to scrape with a plastic ice scraper because of their shape. I tried to keep running the high beams last night to warm them up and they eventually melted but I had to get out and wipe the dirty "slurry" off. I'm wondering if I should just start keeping some de-icer spray and a rag in the car during the winter (wonder if that will damage the plastic covers over time though).
