So then we have a light that comes with the lock kits to show when the lock is active.
That is also connected to the lock power, so when the lock is active the red light comes on up on my gauge pod on the dash.
BUT it does not come on because of the inline diode when you press the brakes.
Now if the diode does happen to fail they can fail two ways (open or closed).
If it fails open my brake lights won't come on with the lock. (not too big a deal)
If it fails closed the lock will activate when I press the brakes, but my light on the pod will also light letting me know this.
In this case I would press the brakes to slow or stop and the lock light on the pod comes on telling me the diode failed and my brakes will only release when I lift the pedal completely and the brake lights go off.
This would be the worst case scenario if the diode happens to fail, but the red light on my pod will tell me the system is in this condition as soon as I touch the brake pedal.
The lock I have is a progressive style, meaning if I have the button pressed for the lock on my shifter I can add holding pressure at any time or even just give enough pressure to resist the rolling in increments (like if you still want the car to roll but not completely freely.)
Don't know any useful reason for using this function except maybe for doing donuts, which I don't do anyway.:D
Another nice side effect is that I can flash my LED brake lights via the button on my shifter without ever touching the brake pedal.
I sometimes use this to flash the brake lights a couple of times as traffic is slowing or stopped in front of me giving a bit of pre warning to cars behind me before I actually start slowing the car.
