I have read just about every thread on this site using your cell phone, digital camera, and a remote for TV. I cannot test my heads to see if they are working. I have the M25 kit bought it 3 weeks ago or earlier. I have this setup with the Cheetah Wireless kit. I have a Hayabusa motorcycle and I have a head in the front and one in the back. I cannot figure out how to get the heads to light up. Can anyone give a little more infomation on getting the head to light up with a cell phone with camera built in. I have the Razr v3 phone, will this work? Are you taking pictures with it to make it fire? Can you explain more on this?
