The light bar on a Mercury Villager, typically located on the rear liftgate, serves as a visual indicator for various functions, such as brake lights or turn signals. It enhances visibility for drivers behind the vehicle, improving safety during nighttime or low-light conditions.

I would check the rear bulbs. I just had this issue and it ended up my brother had used the wrong bulb, and odd enough it caused the brake lights to stay on with headlights. When headlights were not on and you applied the brakes the dash would light and brake lights worked. Strange, HUH? I must admit before this revelation, I replaced headlight switch and brake switch, with no avail.
I have a 98 Villager and I had the same problem. I found that the brake light switch at the brake pedal needed adjusting. Just loosen the lock nut and adjust the switch so that the brake lights do not stay on but only come on when the brakes are applied, then tighten the locknut. Worked for me. Hope this helps.
You may be low on brake fluid. If you are low on brake fluid you may be ready for some brake work or you have a leak somewhere in the system, have it checked soon!
