E brake light and speedo light all of a sudden!?

Ok, I'm going to do my best to describe my "what the hell experience of the morning". So this morning, about 11:30, I went out and cranked the CJ5 up. All is cool until I noticed I have a Speedometer light and the E brake light is all of a sudden lit, I have never had any of these lights and have disconnected every wire I recently wired up to no avail. Jeep drives fine, but I am very worried.

Ideas and suggestions, experiences are appreciated,

Thanks- Ryan

The e brake light can come on if you have a leak in the brakes. I would be checking the fluid fast. Mine can also come on if my e brake pedal bounces down a notch.

Sometimes the tube blockers inside the speedometer fall out or slip so one light bulb can appear to light up another lens, otherwise I am not sure of the second light.

"E" brake lights are controlled by two things. A ground switch on the E brake pedal assembly and the shuttle valve on the brake lines. You should be able to see the former by looking under the dash and inspecting the locking mechanism that operates the brake pedal. Insure the switch is not grounding.
The shuttle valve should be on the brake lines under the hood. In late Jeeps this is usually a combination valve including the proportioning valve about half way up the fender on the drivers side. There should be a wire comming out of the top. Try disconnecting this to see if the light goes out.
Somrthing else to think about, could the light be an emergency drive light for a Q trac unit?
