Hello, My ageing 12v is starting to go crazy, I did the "park lamp relay headlight switch mod" a long while back and everything was ok----- until I swapped my interior lights to LED, now my map lights, cab light and rear bed lights randomly come on all by themselves draining my battery stone flat! I watch them come on with my security camera, normally after the truck sits several days one night they pop on and stay on until the battery's die.....the only connections I can make is that relay I installed that connected to the updated headlight switch a decade ago? Pretty crazy stuff eh. Thoughts?

 

I don't know about the 95, but I'd start by looking at the door switches that control the lights, and if there is a timer module on the truck that controls the light there is a good chance that it is not compatible with all LED lighting. (Basically uses the filament as a ground path and the LED does not offer the same conductivity so the module goes haywire)
