Looking to get my gf led headlights. Any suggestions? I got the truck lite LEDs on my wrangler but want to get her something different.

I'm confused by the comments about ultra-low temperatures.

One of the main advantages of LEDs over other forms of lights is that they're not affected by temperature. (In fact, they get more efficient as they get colder.)

Is there something specific to their use in headlights that makes them malfunction in the cold?

I am not sure if that is true, but if it is, that actually makes the problem even worse.

The question isn't about the LEDs ability to produce light. It's about their ability to melt snow and ice off the lenses.
Very true. We have all gotten use to the fortunate side effect that the waste heat generated by incandescent and halogen bulbs, conveniently melts away the snow and ice off of our headlights. LED's don't produce any where near enough heat to do that. So, as you mention, we're faced with the problem of snow and ice building up on the lenses.

So far, I am aware of only one brand of LED headlight that makes an attempt to solved this, by imbedding electric heater wires into the lens that activate when the outside temp drops below 40 deg F. However, from what I have read, it doesn't work all that well.

Maybe the vehicle manufacturers can build upon this idea. Something like having more powerful heaters on the LED headlights, and activate it when the rear window heater and side mirror heater are activated.

JW Speaker! Can't say enough good stuff about them. I had mine on since February, and they saw some highway and driving snow. I don't remember having any build up issues. Coat them with Rain-x...that'll help. These fixtures with snow on them still beat the OE halogens by a mile.
