I never wanted to change any of my DOT safety lights out for the LED types as this never was a power consumption issue from my battery banks. All the power to operate the safety lights comes from the truck battery not the trailer batteries.
The LEDS are very sensitive and low DC voltages probably back feed into things very easy...
I know my trailer ceiling LED lights sometimes are showing a very dim light even when they are turned off sometimes...
You may have a hard time tracking these events down haha... Most likely all ground related perhaps...
