I just bought these Alpha Rex headlights and put them on my 2015 Toyota Tacoma TRD Off road 4WD. I connected the running lights wiring harness positive to the positive terminal on the battery, ground to ground, and then the fuse is connected to my ignition fuse. When I turn the truck off the running lights turn off and don’t come back on, but when I woke up the next morning my battery was drained.I realized I left the switch in the DRL position. I was wondering if leaving that switch on could cause power draw even with the lights not being on or if there is something else wrong here.
