RE: Watsen Design indicators:
There is a ten LED unit and a micro LED unit. The micro unit, also called the universal unit, is brighter than the ten LED unit, according to Watsen.
Take a look: the two varieties could be mixed front/rear on a bike, I suppose.
The micro (universal) unit carries the extra benefit of eliminating any blink-rate differences from stock.
Another variable to think about is if you want/need the running light function of the original fromt signals to be retained by the replacements.
Talk to Watsen about these topics and indicate what kind of wire junction you need: they will try to set you up for a plug and play installation.
