2015 T660. Reverse lights

[Lonestar10]

seems to be a common PACCAR issue with LED lights i remember someone a while back on here saying their trucks brake lights were on ever so slightly even with truck off. then 2 weekends ago when i was parked for my 34hr there was a t660 parked next to me he had LED lights and when i went for a walkabout i noticed his were on so slightly they were the square LED lights with like 3 rows of 3 or 5 LEDS and they were all on slightly but the led in the very center of the housing was the brightest.

i dont know how the lights work in PACCAR but if they are run through the body controller like international maybe their ran through mosfets or however its spelt and for some reason their not completely shutting down when turned off and allowing a very small amount of current to go to the lights? or if they have chip on board relays same issue? idk. possibly a firmware update from kenworth could fix it if theres a newer version?
