you didnt say your country. ?
as you may not know, lighting rules , vary greatly by country.
so I will answer for usa.
first off the rear brake lamps , on all most all cars run off either a brake switch or a fluid pressure switch.
the dash also has a brake fault lamp which is something quiet different than actual brake lamps in the rear.
you do not have RWAL (2wheel), and ABS (4wheel) is an option. (usa)
the handbrake lamp comes on when the handbrake is on (duh!)
that hand brake lamp is also the brake fault lamp too, like if fluid is low.
did you get a glove box manual with the car.? it explains all that.
i will explain the dash lamp first, it is complex.
first the cluster brake lamp (error) is tested every time you start car.
and if the flluid level is low (see switch in the master cyclinder).
so does the hand brake.
the DRL , day light running lamps also can set the cluster brake lamp glowing. (DRL FAult)
there is a 25 step procedure in the fsm for diagnosing just this one cluser lamp.
last this lamp glows for ABS malfuntion. solid glow = dead abs, blinking = abs malfunction.
i would guess? you car has ABS.
if it does and the fuse is missing then the seller was hiding something.
we should stick to one problem at a time, all this is complex, abs. brakes etc.
lets discuss the rear brakelamps.
there are 6 things that can cause the brake lamps to stick on, or blow its fuse.
1: the brake switch shorted (as you stated)
2:EBCM , abs controller faulted.
3: the shift lock circuit fault.
4: cruise control module fault.
5: 4speed tranny TCM(brain ) fault.
6: trailer lights plug , mangled hacked or wired up badly by some trailer hacker.
i bet your next question is , how to tell if car has abs.
(well you cant test it by braking with your foot on slipper surface , cuz fuse is missing.)
1: look at master cylinder, just near there is this ABS modulator.
it resides , just too the left(driver perspective) and tad higher than master cylinder.
2: tone wheels at each brake rotor
3: mag pickups for said tone wheels, (looks for stalled wheels while braking)
if you car has ABS, and is faulting , you need serious help.
we can not diagnose this complex system on this forum.
if you wish to learn its complexities, my i recommend a FSM, from Suzuki.
factory service manual.
the rear brake lamps are monitored by the cruise , because the brake switch cancels cruise control.
the same with the transmission, it aborts OD if you brake,etc.
the DRL , can fault and it glows the brake lamp to warn you ( they ran out of lamp space)
the shift lock , prevents shifting unless the brakes are applied ,and it could short out
and stick brake lamps on, but is unlikely to do so.
wow that is a hard question.
hardest ever.
always tell country and car drive line so we know what you have, there are 99 diff, markets. i cant guess them.
cheers.
