Default Lighting Problems

So I have a 2014 F-150 STX 4x4 5.0. I have a few problems dealing with lighting/ wiring.
1.) Both my reverse lights work, however the driver side light comes on about 5-7 seconds after I put the truck in reverse.
2.) Neither of my front blinkers are working after I replaced the bulbs with LEDs and turned them on as DRLs and turned off the hyper flash. The lights work as DRLs, however they do not flash when I turn on my blinker.
3.) I could’ve lumped this in with the blinkers, but I think of it as a separate problem. When I have my headlight switch turned all the way off and use my blinkers, both lights flash as if I had my hazard lights on. The blinkers do not flash if I turn on my parking lights, or my headlights.

I’m completely stumped as to why this would be happening and not sure what to do. All the bulbs work, and my parking lights come on as they should. I haven’t found any fuses blown, and I don’t see anything wrong with the wiring.

Did you buy this used? I think someone did some interesting wiring and didn't put it all back properly.

I used Sylvania LEDs for the front turn signals, and factory bulbs for the taillights and reverse lights. I have aftermarket Spyder headlights, but that shouldn’t affect my turn signals. Everything was working completely normally until just a few days ago.

I bought the truck used, but it was completely stock with low miles. Everything has worked completely fine until just a few days ago.

Well, all of this is controlled by the BCM. Suppose it could be going crazy. Maybe reset BCM in Forscan? Otherwise check wiring carefully, perhaps you have loose grounds.
