Intermittent parking light problems

Alright so, recently I've been having some issues with my lights. I have many wiring modifications and splices and after market lights, so that makes this a bit more tricky. My turn signal (switchback LED) on the drivers side has intermittently had some of its LEDs going out briefly/flickering. I'm willing to rule that as cheap eBay lights, but it may be connected. I only notice this when the engine is running. I have led cab lights (these are good LEDs, from SBL) that when I turn them on, are very dim and flicker. When I pull voltage from my battery, I.e. turning on my HIDs or my amp pulling power, they get very dim or even turn off completely. After I drive for a while, they return to normal. For comparison: all five act the same, none seem to differ from the other.
I revved up my engine briefly, and it did seem to make some of a difference.
I even noticed one of my LED tag lights flickering briefly (driver side).
I've had a fog light going out (driver side) but I believe that is from a loose HID connection.

Now my initial though was a bad connection for my parking lights. Or maybe a bad ground. I'll start looking into these when I can put it in my basement to get out of the cold. But another thing that could be a possibility is the CTM. Now I've had issues with my CTM before, and there is a TSB that applies to my CTM to replace it. I also noticed one time my interior dinger was off time/going out.

I'm looking for suggestions/opinions on what my problem is. Any help is appreciated

I just remembered the temporary fix for the CTM, so I'm going to check that real quick

Update: CTM does not see to be the issue. Reset it, no difference. Also, looking online the CTM doesn't even control the lights. Doesn't explain my dinger, but I'm not as concerned about that. Only happened once.
Checked the fuses associated with the lights, nothing.
However I did tap my headlight switch, cab lights flickering. Loose connection. I'll pull that off tomorrow

I could be wrong, but maybe you are pulling to much power for all of those accessories to be running at once? What do you think?

Your alternator may not be able to provide enough power.
Maybe you could add in a capasitor (can't spell or google) or an additional battery?

This came across my mind, but most of the extra lights are LEDs, and draw very little power. I'm fairly certain the problem is in that connection, as I said I saw the lights flicker when I tapped on my headlight switch. At one point it was fully fixed

The headlight switch will be a good place to check, our 2000s aren't prone to those problems with them are they?

I know people had problems with them. Not sure years, but definitely a good possibility

definitely keep me updated with what you find out. What kind of bang do you have in the truck?

Cab lights fixed. Found a loose connection behind the switch where I spliced it.
Fog light seems to be acting fine now. No longer is the connection loose.
No issues with the interior dinger as of yet .
Found a loose connection at my tag light, it's working normally now.
And my switchback.. I'll assume that's cheap parts. Already have my SBL ones I just need to get around to doing that.
All is well now

Bang..?

Bang like a boom stick(gun)! Hah, I meant what kind of amp/ Subs head unit are you running.

Rockford ftw! Lol the only stickers I have on my truck besides my parking decal and sport vinyls are two red Rockford stickers in my two quarter windows along the bottom edge. And I hate stickers if that means anything.
