Headlight / taillight question.

[macadoe]

My wife just went to move the golf cart and I noticed that when she hit the accelerator the tail lights lit up very dim with the pull switch off, just both rear led not the front which are not led. They work fine with the knob pulled on. I have the negative to the voltage reducer coming from last battery and 36v power coming from key switch. The kit came pre wired all I do is hook up power. They are barely lighting, but they are very dim. Never noticed it before. I don't want to hook it up directly to batteries because of kids around may play with it and leave it on and kill my batteries.
