Wow, so many people responding to my questions, thank you very much.
All the lights are working. It's only the brake lamp light stays on all
the time! This happened before about 2 years ago, corrosion on the bulb
and the socket. I cleaned it and was fine till now. I took the bulbs
out ( except the centre one), measure the resistance, they seemed very
close in value.

My guess is that it tended to not work properly.  The brake lamp light in my
'93 Accord sometimes lights up in cool, damp weather after it has not been
driven for many hours.  Perhaps condensation is the culprit.

totally forgot about that.  That happened on the GFs 87 prelude, but my 98
does not have the feature that warns you when a brake lamp is out.  Wonder
why?

First, if all your brake lights at the rear of the car are working
normally, then the module is fine.

If this is the "brake light out" warning light on the dash that's on, then
you should check the center high-mount brake light. Everybody forgets that
one.

If all your bulbs are in fact working, then you've likely got corrosion on
one or more sockets that is increasing resistance such that the control
unit *thinks* a bulb is burned out, even though it's not. Remove all the
bulbs to check for rust.

The brake lamp stays on after I step on the brake. It is a 90 Accord. I
have checked old postings. I have checked all the bulbs. Some suggest a
greyish sensor or a module. All I can find is a greyish connector very
close to the bulbs on both sides. I have traced the wires to the rear
back seat but can not find the 'module'. Can anyone help me with that?
Very much appreciated. The red light is there all the time, very
annoying. Thanks.
