Mark, they do not change brightness unfortunately. There is another
disappointment with them and with which I live and that is they glow
green(charging) at 13.2 V and they WAIT to go to flashing Red'Green at over 15
V.
I've tried to contact the one vendor with whom I've bought them to encourage him
to recalibrate the voltage triggers to the correct 13.8 and 14.6 V. So far not
getting through but still trying. I'd welcome anyone else to try contacting a
vendor-I think there are several (probably all coming out of China)
I live with the errors since I can't change them but I also know where my KLR's
voltage regulator is set even if the triggers are lighting up too early or too
late

Hey
1. I do NOT remember making any such coments about that.
Mine was about a bypass switch etc.
2.FRED!!!!! I agree with the stocking issue, I'm about to buy 2or3.
several other companies charge ALOT more then $1785 (+$2.40 shipping from the
UK.) listed on Ebay.
I do not remember if Johns changed brightness from day to night, But it sure was
nice to know what was happening. AND NEEDED A FEW TIMES.
but I like that alot also about this unit. (they have smaller or larger ones.
5mm or 8mm led lens, 8 is 1mm total showing on dash etc.)
I had to get a push this fall do to drained battery, (GPS Heated grips AND
Gerbing coat liner)

and sure won't today or for the next predicted 4 or 5 days...
well at least it gives me time to catch up on email
and planning for doing my do
