I have on both my bikes LED running lights (on all lights),
I'll take a couple of pics today and post them here.
I didn't buy the ready bulbs but actually made them myself.
I just order online a 50 pack of standard white (5mm) 12V leds
(along with a resistor for each) and wired them into place.
I did this to save watts because on my yamaha I'm running
110watts up front and my system can bearly handle that load,
so this hepled.
On my little bike (a 50cc, 5hp, 2-stroke aprilia scooter)
it didn't have any running light anywhere to begin with,
except the stop light, so that's why.
