...until it starts snowing. I had Trucklights on my Jeep and they were phenomenal...until it snowed, or even rained sometimes, heavily. At that point, all the light was reflected back into my eyes and the lights got covered. I had to pull over every 5-10 minutes in extremley heavy snow to wipe off the lights. I know they make heated versions now, but I highly doubt they are included as OEM.
