Eiminate the guesswork if your block heater is working before you even open the cab.
One led shows you have power coming in.
Second led is telling you block heater is working.
This one here shows the block heater is junk for reference
If you park all your trucks in line
Can look from your cameras and be able to see they are all working haha
Just figured I'd share with how cold it's been this winter
