Here's the body of an email that I sent to email@example.com:
"I have just received a MH-818 tail light "add on" package. I can't get it to work. I have plugged in the Y-cable. My headlight works on both legs of the Y. That tells me the the battery and the Y-cable are both working fine. I can't get the tail light to do anything.
According the the website, it looks like all that I should have to do is turn the silver ring to turn it on. I've done that, both directions with no results.
Am I doing something wrong, or did I receive a defective light??"
Here is the next correspondence that I had with them:
"Nevermind, I just returned it."
I figure in today's "rapid response" world that 24 hours is enough time to get some sort of answer from a "manufacturer" (distributor) to a customer that is having technical problems with a brand new item.
