No need for anyone to drop more than $6 for the same thing but in a different form. Look up the PaceBeeper app on the IOS app store. Set any interval you want, any time you want, how often you want it to beep, and you have an audio sound. Every time it beeps, you should be at whatever pre determined distance you set it up for. Pretty standard to set it to 50m intervals, when you hear the sound you should be at one of the 50m marks on the track. If you can't keep pace over 50m and need a light to see the entire time your running, track might not be for you. Play it over loud speaker.
I've done this. It works, but I didn't have the cones close enough. I had them at, IIRC, every 50m. It was depressing to suddenly miss a split by 4-5 meters. If I try it again, I'll move the cones a lot closer together.
