Hey guys just reporting back on some excellent customer service which deserves praise. I bought a set of LED hyperlites from Black Dog Cycle Works nearly a year ago and noticed recently that one module has gone down. I'm overseas in the UK and had a bit of trouble getting hold of Hyperlites initially. One email to Kurt at Black Dog and within an hour I heard back from him to say he had made contact with them on my behalf and they would be sending out a warrany replacement. It's now on it's way to me thanks to Joyce at Hyperlites. It's great when suppliers respond to their customers like this. Thanks you both !
