Richard.... from the front - oncoming traffic - the amber LEDs in the mirrors are MUCH brighter and noticeable than the OEMs.
(Mind you, if you put LED bulbs in your OEM blinkers, they are much brighter, too. Straight bulb swap, about fifteen bucks a bulb....)
From behind, the mirror LEDs are red - probably illegal in OZ?? Should be amber??? - who cares? - They are high, wide, and handsome (like the rider) and BRIGHT. At shoulder height, they gotta be hard to miss.
And of course you can't miss it if you forget to click 'em off......
Footnote! Just fitting the mirrors, your standard (cheap ****) flasher can would probably work. But if you replace blinker bulbs as well with LEDs, you're gonna have to spring for an electronic flasher can.... maybe twenty five bucks, straight swap over.
Ponters.... no mention anywhere about e ratings.....
