Pool Light

[matt4x4]

What brand of light is it?
The aqualuminator should NOT do this, however, if you/they did not tighten it enough, there could be a very small leak around the gasket separating the electrical portion from the return jet portion, which in turn could conduct electricity back into your pool.
Let us know the light brand and we'll be of more help.

Are you plugged into a GFI outlet?
What type if light?
As Matt mentioned the aqualuminator should not shock you it is running on 12 v DC and doesnt have the punch to get you.
