I recently installed a set of Tuff Lites on my F650 Dakar. Love 'em—they're nice and bright and seem durable although I haven't eaten it on the bike since they've been on there. I was able to use my stock flasher with no speed issues, although I understand earlier F650s have an old-style relay that won't work.
I wanted to share the excellent customer service I got from Scott at EDS. I emailed because I had installed the signals and they were all coming on, rather than just one, which happens on some bikes due to juice being fed back from the single indicator light on the dash. I got a reply from Scott in less than two hours, on a Sunday
, saying he'd send me their turn signal indicator wiring harness for free
to see if it'd work on my bike, if I'd just confirm either way. It didn't, but that's ok—I just took out the li'l indicator bulb on the dash. Good to go!
Overall, a very good experience, from order to install to support.
