Hmmm. I wonder how Audi and BMW who have been using them for years go on?

Needs headlight warmers :p

Does the frost compromise focus of the lighting much?

I wounder if a seal is broken and letting moisture in? My RX-8 and many others had moisture issues with the tail lights.

Exactly what I was thinking. And yet there is a heat sink at the back of the light???

Without good heat sinking, the internal (junction) temperature of an LED rises, and this causes the characteristics to change. As the junction temperature of an LED is increased, the forward voltage, lumen output, and most significantly, the lifetime of the LED decrease significantly.

It's a pity some of the heat can't be wasted in keeping the headlight warm.

Of course it does and also light output in general.

Both lights have the same problem. Frost melts if you can use HI-beams (more heat) for a longer period.

I haven't noticed this issue with mine, but it hasn't gotten quite that cold in Colorado so far this winter. I'll have to keep an eye on it.

We'll have to come up with another method to defrost the headlights. Can't high beam in the city for an extended period of time without blinding someone.
