I replaced my interior lights with LEDs and put led strip lights under my side mirror so I can see outside of the car at night.

Also if I take the interior light fuse out the one light on the inside and the 2 led strips still do the same thing.

Ur connected to the armed feed wire to the cars anti theft Go off the acc positive 12+volt feed to a switch to ur accessorys ground to frame not bat n it went back feed n shold free up ur circuit problem

U have a short In that circuit start at powesourse check for shorts. Wires touching. Then while fuse is out check voltage put n fuse if no volt drop u on wrong fuse or ur on off switch is shorted to power on position or power wire shorting to sourse

The thing is with the outside lights there are hooked up to my old light wires where the old interior under the dash were

I pulled the fuse out and hooked up a digital volt meter and was getting around 1.7 volts to the lights that run off the security
