You don't need to go ripping things apart at all. If you don't need your lighter, well there won't be a problem. I would think though (I'm not sure,as I don't use my lighter) that there is always power to it and you may have to have some other on/off switch in that situation.I must ask though....why would you want lighted pedals??
To be honest, the lighted pedals came with the car but were never hooked up....so I figured I might as well make 'em serve their purpose. As for the lighter...it seems that it doesnt stay on when the car is off (I'll double check), so it should be good....i plugged in my phone charger to see if it worked, and the "i'm charging" light came on only when the car itself was on, and went off with the car, so i'm assuming that lighter power goes off with the vehicle.
