My 2020 mitsubishi outlander sport had a dead battery after sitting for 4 days. I installed an aftermarket amp and put the remote on wire to the fuse box which is a fuse to the radio. That had to drain the battery since the radio fuse is with the alarm. Jumped the battery and it started right up. Then the LED fog, low and high beams won't turn on. Switch is on. Dash light shows they are on. Fuses are good. Parking and turn signals work. Is there something I need to reset?

 

If your LED lights aren’t working at all, the bulbs themselves may be the issue. Although LEDs tend to have a long lifespan, they can still burn out or fail.

 

There may be a problem with the electronics. The best answer will be given by an auto electrician
