Funny (no ha ha), car lamps are burning 110 watts and seriously hurt if you get a straight on shot down the optic nerve. Those hurt me more than even the white hot LED lamps.
Just can't see (pardon the pun) your lamp really blazing anyone, looks like it's aimed down pretty well. Wonder if he was riding uphill as you crested and you got him. Anyway, seems a overreaction.
Nice set up , hows that lamp work in fog? Looks like the low mount would do pretty well.
