My brake light are always on with the engine running??

Yea, I did a search, and all the brake light threads I found were for non working brake lights or just one side working.

Today I was checking my oil level at the dip stick, and I noticed the brake lights are just on. I had my wife stand behind the car, and hit the brakes and no change.

I do have Spoke's LED boards as my brake lights. The brake lights have been working just fine for years. No changes, no electrical work done in many months.

I know there are two pressure switches on the master cylinder, but those usually fail and the brake lights don't come on under light braking. This is not that issue.

So, any ideas as to why the lights are on all the time when the engine is running. And yea, as soon as the engine is turned off, they go out.

I will send a PM to Spoke and see if he has any ideas on a cure.
