Can I use a relay to wire lights to a speaker?

[QUOTE="latlog7, post: 8574209, member: 673155"] Okay, but I do understand the difference between AC and DC; just hear me out. So when the speaker plays, the current will be alternating very fast correct? Now if we analyze one sinusoidal cycle of the AC current, we can see that there are times when there is instantaneously no current. In theory, assuming an ideal relay with instantaneous response, this will cause the relay switch to be open when there is 'no' current. But for an actual relay, there will still be this rapid on/off, but it should be offset by a minuscule amount of time. However, the [B]rate[/B] should still be the same. Now the human eye cannot interpret changes much faster than somewhere around 60 or 100Hz, so, (unless im using like 20Hz speakers) the lights should appear to be constant with the bass speakers. But I just wanted to know if I was overlooking something. What exactly is wrong with this idea? [/QUOTE]
