Jack,

=20

I had a 55 TR3 with the lights as you described.  I put a separate small =
red LED (pretty bright, actually) inside the lens of each of the outer =
fixtures.  I got them from a local electronics store.  I epoxied it to =
the base and wired it in parallel with the existing center brake light.  =
It was pretty easy to do and the result was three brake lights that came =
on at the same time.  The regular dual filament bulb still worked as =
normal with the parking light and turn signal.

=20

As a side note, some of the MGA=E2=80=99s (not all of them, but just a =
few years) had a special electrical box of some kind under the bonnet =
that allowed three functions using the two filaments in the rear outer =
lamp assemblies.  I first noticed this when I saw an MGA with just the =
outer assembly (no brake light in the center), similar to our =
TR2=E2=80=99s and 3=E2=80=99s, and it had the standard two filament bulb =
on each side.  I asked the owner how he got three functions with only =
two filaments and he shrugged his shoulders.  He had the wiring diagram =
with him so I looked it over and it=E2=80=99s a solid state (I think) or =
electro-mechanical black box device that allows a dual function for one =
of the filaments.  I=E2=80=99m guessing that it was the brakes and turn =
signals on the same filament, but not sure.  Still, it was pretty slick. =
 I was more curious than anything so I never looked into it further.  =
That was a few years ago.

I have my street TR3 wired that way; so the corner lamps do triple duty as
tail, stop and turn.

You can buy a solid state device to do the conversion (commonly sold to
connect a "3 wire" trailer to a car that has separate turn and stop lights).
However, I did mine with relays.  Initial conversion was done with only two
relays, but then when I started converting to LED lamps, I re-did it with 3
relays.  Here's a brief schematic
https://i.imgur.com/WWBJhUE.jpg

FWIW, this was done with no permanent modifications to the car or the
original wiring harness.  The relays are mounted under the dash, out of
sight, on the back of one of the bolts that holds the brake pedal pocket
together.  A new sub-harness runs from there up to the area where the
control head wires join the main harness, plus one wire to the brake light
switch.  (Which in my case is still under the dash, as I converted to a
mechanically operated switch instead of the original hydraulic one.)

The relays are just cheap automotive relays; couple buck each on flea-bay.
(ISTR I bought 10 of them, with sockets, for $20 with shipping.  But I've
decided I don't like the sockets, so I just use quick connects to wire to
the relays.)

Anytime the surf sucks in Maui I’ve been working on control systems for the electrical stuff in the 1978 GMC moho I’m updating. One component is a wireless brake/turn/tail/backup light using an ESP32.  The turn signals are sequential. Seeing sequential turn signals in a little Lucas taillight would freak people out. If you weren’t going to do all the wacky wireless stuff it would be easy to combine features with an Arduino and a few MOSFETS, or better yet a mosfet board that includes opto couplers. The code is pretty simple, though my current version is written for using MQQT via wireless—for any geeks out there.

> Metal oxide semiconductor field effect transistor I think. 
> That's about all I know about MOSFETs!

MOSFETs basically have a very thin layer of glass between the control
element and the rest of the transistor, giving them a very high input
resistance and hence easy to control from a microprocessor that has only
logic level outputs.

They also can be designed with very low resistance in the ON state, making
them ideal for handling high currents.  I use some older ones (that I got
for free) that are good to 12 amps or so; while there are versions available
that can handle 500 amps (probably even more by now).

Didn't really need a MOSFET here, but that's what controls the center brake
light in this (very brief) video
https://youtu.be/q4GMcD9DktQ

But unlike Bill, I didn't bother with using a microprocessor.  The 4 blinks
are provided by an old fashioned NE556 integrated circuit.  Sometimes simple
is better.  The entire circuit, including active current limit for the LEDs
and some more LEDs to provide a license plate light (not shown), is located
inside the center brake light.
