Yeah, hopefully your days of delivering fish in snowstorms are past you!


That's true, LED's don't generate hardly any heat, yet there are almost no tail lights on any car that will melt snow, due to recessed bulbs and mult-layer tail light designs preventing heat reaching the outer acrylic cover.

The upside is brighter, far longer lasting lights. Plus, with the new USDOT/FMCSA rules on individual commercial drivers now being "safety rated", even a warning for a burned out bulb reduces a driver's/company's FMCSA "safety rating". Insurance companies are now using this info to raise premium rates. The new rules are almost insane, so longevity is paramount for long term cost exposure. A simple, burned out bulb even on a cab roof, can raise insurance rates on a commercial vehicle the same, or more, than a 20MPH over the limit speeding ticket does for any of us.
