Will Putco Luminix LED Bulbs Be Warm Enough to Melt Snow

Question:

Since we live in the Midwest is ther a problem with ice buildup do to the lack of heat produced? We have had issues with ice build up on traffic lights that have been fitted with LEDs. Is Dot Compliant the same as Dot Approved? Are they capable of daytime running lights as are my factory lights?

You ask a really interesting question.

Its absolutely correct that LED lights will generate much less heat than typical halogen headlamp bulbs, due to their better efficiency. In even really cold Midwest winter weather a halogen lamp will usually keep the outside of a car's headlight lens slightly warm to the touch. This will be enough heat to discourage buildup of snow/slush/ice on the lens. On my car with halogen bulbs even if I start my morning drive with ice on the headlamps (that might have accumulated during the night) by the time I complete my 16-mile commute that gentle heat will have my lights mostly clear.

I checked with my technical contact at Putco about your concern. He advised that the black billet aluminum base on the Luminix lights, which acts like a heat sink to cool the diodes themselves, will itself warm up once the lights are on for a bit. This material will tend to retain this heat, unlike the plastic base of a halogen bulb. So the result will be slightly less heat at the exterior lens surface but still enough to melt away most of the snow/ice that might land there. It will take a little longer to initially melt away any accumulated snow, but once warmed the lights will have enough heat to remain clear of build-up.

Yes, the terms DOT-Approved and DOT-Compliant mean the same thing, and yes these USA-made Luminix LED headlamps will work fine for daytime running light use.
