Funny short circuit

[dibbons]

All lights work fine on my '65 Signet convertible. However, with the engine off, key removed from the ignition, if I step on my brake pedal, the dash lights come on, let off the brake pedal, the dash lights go off! Weird.

 

[AJ/FormS]

Do the brake lites come on as normal, key off?
Do the dash lites work like normal, key off?
Does the car stil have the original column and wiring?

If entire park lamp circuit is coming on ( tag lamp, etc.. ), One possible cause is lack of chassis ground at rear lamp fixtures.

You either have poor grounds at the rear lamps (most likely), or a single contact bulb (1156) in a dual contact socket (1157)..

One of your tailamps isn't working properly..

Clamp the bare end of a length of wire to your trunk striker,, take the other bare end and touch it to your taillite bulb bases, re-check problem..
