I read that you can find these Y-Socket things http://chiefio.files.wordpress.com/2011/01/dscf0568.jpg at Walmart, but I haven't had any luck online or in store. Where can I find these things?
I found some at my local hardware in a town of less than 2000 people, so I can confirm they're available just about everywhere. If you can't find it in walmart, try lowes or home depot. If you can't find it on your own though, just ask an employee to help.
Home Depot has them in a box on a shelf and as many as you ever would need. Go to amazon.com type in y light adapter...plenty on there to.
