Before you start looking at the electronics, you should buy a pack of
taillight bulbs and see if both main brake light filaments did actually
both blow out at once. Worse come to worst, you'll have only spent
$2.75, and you can stick the bulbs in a drawer, and someday you'll blow
out a bulb and you'll already have the replacement at hand.
For one thing, you could have had two of the three bulbs blown out for
weeks but you never noticed. It's easy to miss a burned-out tail
light. For another, I've had both tail lights blow out "at the same
time" (again, I noticed them both out at the same time, which doesn't
mean that I wasn't driving around with only one tail light for a while)
and I have also had both head lights go out the same night. I
definitely noticed that when it happened, and I thought it had to be a
bad switch or relay or fuse, but no, it was two sealed beams that let go
within minutes of each other.
Good point and thanks so much!!
I will replace all the bulbs in both rear lamps and
work from there.
However, if that doesn't fix it..... can you tell me if
there is a RELAY that controls those lights from the
brake switch? I've looked for a relay but yet to find
one. Is it possible the lights are controlled direct
from brake switch?
Also, what abt the feasibility and cost of replacing
the bulbs with LED version? Not cost effective yet?
I can't tell you about a 2000 Protege, but according to the '99 Miata
Workshop Manual there is no brake light relay on one of those, just a
brake light switch mounted at the top of the brake pedal lever. And
when I looked in Google for "2000 protege brake light switch" I got a
zillion matches where you could buy one (they're cheap too) but for
"2000 protege brake light relay" I got nothing but noise, so I'll bet
there isn't one on your car either. However, another semi-random Google
match I did see said that Protege brake lights are all on one fuse, so
if you can find a map of the fuses in your car that's the first and
easiest thing to check. Good luck!
I don't like the way LED tail lights look, the soft bell-shaped shade of
an incandescent bulb through a traditional red lens is far easier on my
eye, but as brake lights LEDs are technically superior because their
response time is practically zero as compared to a quarter-second for a
classic Edison-style filament. When it comes to informing the moron
tailgating you in his SUV that he's about to get his insurance rate
raised after he runs you over if he doesn't pile on the brakes RIGHT
NOW, every decisecond counts. How much is that worth to you?
Guess what guys..... this was the problem!!
I replaced ALL lamps in rear tail lights and now have
working brake lights again!!
I guess above poster was correct..... the lamps did NOT
go al out at once but must have gone out one at a time
and as long as one was working then no one stopped me
to tell me. When the last one went out.... an older
lady stopped me to tell me I had no brake lights at
Bottom line I am deeply thankful to ALL who offered
Now I just have to figure out why cruise control quit
abt a month ago

The cruise control probably gets 12 volts through the bulbs when you
aren't braking. It sees 0 volts when you apply the brakes. If all
the bulbs are burned out, it sees 0 volts all the time and thinks you
are applying the brakes all the time.
i would first identify other things that may not be working such as the
running lights, directionals (fast blinking is an indicator of a problem),
interior lights, etc.
i don't know the protege, but the miata has one fuse box under the dash by
the drivers left knee and another under the hood.
i recently lost all of my tail lights and checked the interior fuses with no
joy, then found the main relay in the engine compartment fuse box had jumped
out of its socket.
if it is of any value, you can download the 2002 protege workshop manual for
free from here...
but it is in rar format so you have to have a rar utility (free) to
reassemble it, and it is on rapid share, so you have to download each of the
three parts about an hour apart (unless you are a paying rapidshare
that 2002 workshop manual has excellent step by step troubleshooting and
repair procedure starting on page 01-02c. it appears that the lights can
fail if there is a problem with the cruise control module. is your cruise
No.....as a matter of fact my cruise control does NOT
work and quit working several months ago!
I can hear the relay click when turning it on but it
wont allow me to setup any speed. I just assumed it
was a blown fuse and would replace it when weather
How in the heck are the cruise control module and brake
lights tied together so as to make the brake lights to
Don't know but Mazdas are like that. Now start checking fuses, look
for any blown fuse. It'll probably be labeled as something
completely unrelated to either the stop lights or the cruise
I don't recall exactly what problem I had but I checked every fuse
that could in any way be related to the failure and finally gave up
(Checking Miata fuses is easy only for people less than 10" tall!)
and took the car to Mike's Place: http://www.mikes-place.biz/
I would have ended up there anyway, Mike is the only one who has ever
been able to put my fuse box cover back on.. <sigh>
He knew exactly what fuse it was but the label was for something
very different... :-(

Since the cruise isn't working, I would go straight to the stoplight
switch on the brake pedal. Mazdas with cruise have a combo switch that
is both for disengaging the cruise and actuating the brakelights. It
should be located about halfway up the brake pedal arm. When you are
replacing/adjusting, please note that the plunger on that switch must be
fully compressed (when nothing is pushing on the pedal) in order for the
cruise to work at all.
OK thanks will do!
However, since the car is 9 yrs old and have never
changed any taillights I'm going ahead and change ALL
lights front and back since it is summer and easier to
Knowing my luck even if I get the brake switch fixed, a
bulb will burn out say in dead of winter and much more
unpleasant to change then as I have no garage.
Also, one of the bulbs had odd ball socket "tabs" on it
that were NOT 180 degrees apart but instead more like
120 degrees apart! So had to have Oreillys special
order them . <sigh>
since your cruise control is not working, i encourage you to download the
service manual and follow the problem resolution procedure. it seems very
straight forward. it would be nice if changing the bulbs helped but i think
that is a fantasy. fwiw, stepping on the brake is the most common way to
deactivate the cruise control, so it seems reasonable that there is an
interaction between the two, though it seems odd that they didn't design the
switch on the brake pedal with multiple distinct functions (one circuit for
lamps, one for cruise control), probably saved a few pennies by making it a
single function switch, but might have been some sort of safety feature that
escapes my imagination.
you should download the entire manual, it is really good.
but if you want me to send you the couple of pages then email me privately.
the manual does have the information you want with graphics for the hight
mount brake lamp, and for the spolier version as well...
