If the object is sealed then transfer of a contaminant or metalization by sublimation occurs between a warm 'emitting' surface to a colder 'receiving' surface. This contamination process is progressive and non reversible.
Rubbing salt into the wound is the fact the cheap $100 Chinese leds I have don't fog up like these $385 Made in USA lights.

There is a difference in perception of objects/distances with these new lights. Compare an LED flashlight with a standard (filament) flashlight in total darkness; it takes a while for the brain to compensate the monochromatic light source. I'm staying with my H4 and two H7 bulbs.

It is a very defined light. Great for straight sections of road as it lights up a long, wide area without blinding oncoming traffic, but definitely not good leaned over in corners. What I would recommend you do is add a couple led driving lights that have a conical beam and aim them toward the sides.

Accurate product specification and ISO certification for quality assurance apply everywhere as long as you pay the price.
What we pay is mainly driven by our pride of ownership and acceptable profit objectives. In China I discovered high quality products that are not offered to us Westerners because culturally we will not invest in what others cannot see or recognize the value.
Times are changing: do you remember the days of low cost Japanese dolls and alarm clocks
I get what you mean. But actually the Chinese lights are definitely crap, I had a number of them stop working on my other bikes, stopped getting them when the year warranty ended, but for some reason they are surviving on the RK.
But the Piaas I have on my Super Tenere have been excellent. They're made in Taiwan. $191 for the LP530s, $265 for the 1100 LEDs on Amazon.
The old units used "sealed beams" ... The new units use halogen bulbs and therefore are prone to fogging ... The original passing lamps ( replaceable filament type ) use 25 watt form the factory ... I replaced them with 37.5 watt ( 50 watt are available also ) and am QUITE HAPPY with the results ... and a whole lot cheaper than the LED's .
Twinrider, I was thinking of doing something similiar. What kind of light did you use for that application? I run lower fairings year round so that is something else I have to contend with when or if I mount lights like you.
I bought them in 2012. The box they came in says 73396-10A. I first noticed the problem this spring. The fogging only occurs after the lights are on for a while and heat up. The condensation forms a wide frosty looking oval shape on the upper half of the lens. Turn the lights off and after a few hours the fogging goes away completely. It returns again when the lights are turned on for a while during your ride. I am almost absolutely certain they did not this when new. So I believe it's a problem that grows over time due to moisture somehow developing inside the sealed lamp. Both lights show the same exact fogging pattern.
