Brake warning light on?

    I have an Econoline E350 2001 7.3 L, which has a strange problem with the illumination of the parking brake dashboard. While I'm driving along the road randomly, the indicator on the dashboard will turn on and off. Sometimes it fades out, and sometimes it just turns on.

    This symptom has been observed for some time and finally begins to upset. When it turns on, it will also kill my cruise while in use.

    I have a new OEM vacuum pump installed and it didn't make any difference.
    Disconnected the parking brake switch without any difference.
    Disconnected the brake tank sensor without any changes.

    Not sure what else turns on this light?

    Any ideas will be highly appreciated.

    I had a similar problem. The whole thing turned out to be a faulty wiring. Then it was night and it was good that I had a good flashlight thanks to which I was able to quickly find the fault.

    Perhaps the problem is simply this bulb? Analog light bulbs often don't work correctly. That's why many companies are increasingly trying to do away with them and switch entirely to LEDs. That is undoubtedly encouraging since technology does not stand still and is getting better every day. Even now, the difference between conventional bulbs and LED bulbs is vast. I recently purchased an LED lantern on this site and saw for myself how different the technology is. The difference in luminescence is vast. One such lantern shines as bright as 3 or 4 regular ones. So you can thank the people who are working to improve the lives of all humanity.
