I'm leaving on 10 day trip in less than 24 hours. I have some trail tech lights that I bought from an inmate, and I'm looking to install them in a hurry. I have an existing centech aftermarket fuse box wired directly to the battery. Can I simply: ground each light, run power from the fuse box to a rocker switch, and power from rocker to the lights? It would be my preference to have them work with the key, and I know I will need to be sure to turn them off, but is there any problem other than that? Alternatively, can someone point me (an electrical noob) to the easiest way to get power to the lights directly (as in, they turn on with the key)? Thanks for the help.
