I just put one of these on eBay (http://tinyurl.com/dg4zbm). I've replaced all 4 turn signals with these clusters and am very happy with the results. Only 0.3 amps power at full intensity. This was a spare that I don't think I'll need since the LEDs should outlast the bike. I used the existing OEM bulb bases to install them (broke/removed the glass bulb and wired in the LED).
