Many thanks Marv, that is by far the BEST picture I have ever seen of what
looks to be a genuine original FL3 Flasher – wish I had of had photo before
XK140 EXPLORED was published as all I could do in this was provide an
overall outline shape, but without any of the black ink lettering – period
LUCAS catalogue photos I had certainly showed lettering to be black ink but
just impossibly fuzzy to make any sense out of it, so thought best not to
try.

S815690BW is a May 1956 date-of-manufacture, so date on your Flasher unit of
10 55 is not inconsistent, especially given it was around end of 1955/early
1956 that the FL5 apparently superseded the FL3 in Lucas production,
although I dare say some lag before the change over happened on the Jaguar
line.

My XK140 is a Sept 1955 build and it came with a replacement FL5 flasher
unit, so I have been on lookout for ages to find an FL3. In Australia at
least I do come across the occasional NOS FL5 with screw-in terminals,
although usually found with later LUCAR connectors, but so far never an FL3
– in any condition.

Roger,

from “the for what it’s worth dept” S815690BW came with a FL3 flasher when
I acquired it in 1970. It was functional then. (maybe now?)

Thanks Gene,

And of course you are correct - I just sometimes get lazy with some
convenient simplifications, and loosely the change over in Lucas supplied
Wiring Looms from Bullet connectors to Lucar connectors in Jaguar relevance
was conveniently with the introduction of XK150, fortunately with
transitional aspects re various componentry all with XK150, and nothing with
XK140.

Roger,

Is the Lucas FL3 Flasher similar looking to the Lucas FL5 Flasher?
Also, do you know the difference in the electrical
specifications/capacities between the two Lucas flashers?

The XK120 Spare Parts Catalogue, p. 85, specifies the Tung Sol
241/D Flasher. I understand that these were rated for operating
two 21 watt lamps at 12 volts

Urs Schmid’s Volume 1 XK120 Book, p. 178, states that the Tung Sol
Flasher was replaced by the Lucas FL3 Flasher in 1954.

My November 1953 XK120 has a Lucas Flasher with screw terminals.
I’m wondering if it is an FL3 or FL5. I should pull it out so I
can read what it is as well as the date of manufacture.

I am only guessing, but given it was US demand that initiated fitment of
flashing indicators to late XK120s, chances are the initial solution was US
developed/sourced - thus the Tung Sol 241/D flasher unit listed as you say
on page 85 of J.8.

I would presume Jaguar would have had Lucas working on a local solution as
soon as possible, as the intended legal introduction on XK140 was looming,
and that fits in with the Lucas FL3 Flasher Unit being used on the first
XK140s, and would seem according to Urs, also the last XK120s.

The XK120 Lamp arrangement was pretty simplistic/basic but Jaguar seemed to
be on the run with this as the very first XK140 Flasher Lamps were the short
lived Lucas L.539 model, rather than the familiar L.563 model.

Seems as though the FL3 Unit was also very short lived, being replaced with
the FL.5 unit in 1955 and this improved unit prevailed well into 60s/70s and
was a service replacement for FL3 units as well.

The pics Marv Moore has sent me clearly show the FL3 flasher to be rated 12v
36 42 watt whereas the FL5 is rated just 12v 42w which of course is
consistent with driving two 21w flasher bulbs used on XK140/150. What
bulbs flashed in an XK120 so equipped?

Be interesting to see what is on your Nov 1953 XK120 - and component will be
dated.

Thanks Charles,

I am getting lazy and could probably find info in my various books, but was
interested in the wattage of both front and rear flashing bulbs.

The XK140 has 21W front and rear flashing bulbs - the rear of course being a
twin filament with brake light, with the FL5 driving these as you would
hope/expect a 12v42w rating.

I noted that the FL3 from Marvin’s photo had what appears to be a lesser
12v36-42W rating so am guessing maybe this was enough for the XK120 bulbs,
but insufficient for their more purpose orientated overall XK140 design,
which may explain the disappearance of the FL3. But I am guessing.

In reply to a message from Roger Payne sent Tue 3 Apr 2012:

Looking at the XK120 Spare Parts Catalogue, it appears that before
the use of ‘‘Flashing Indicators’’ the front sidelamps were 6 watt
and the tail/stop lamps were 6/24 watt (Lucas # 353).

After the introduction of ‘‘Flashing Indicators’’ both the front
sidelamps and the tail/stop lamps became 6/18 watts (Lucas # 361).

So the introduction of the ‘‘Flashing Indicators’’ caused Jaguar to
reduce the wattage (and safety) of the rear stop lamps.

The later introduction of the FL5 Flasher with a 42 watt capacity
probably allowed Jaguar to increase the wattage of the rear stop
lamps. The ubiquitous 1157 dual filament lamp is rated at 8/21
watts according to my Google search.

Thanks Mike,

But that says it all doesn’t it - if the XK120 flasher front and rear bulbs
are rated at 18watt, then that fits in with the lower end 36W (2x 18W)
rating of the FL3 Unit rated at 36-42W. This may well be reason for the
higher rated FL5 being introduced, as with XK140 both bulbs were 21W needing
the higher end Unit 42W rating.

May also explain why you rarely see an early XK140 still with its
“undercapacity”, or more likely “marginal-capacity” 36-42W FL3 Unit, and why
Lucas discontinued the FL3 replacing it with the 42W FL5.

The flasher unit is listed in the Mark V parts catalogue as simply 241/D
Flasher Unit, and given that the Mark V was the first model to be frequently
equipped with flashers for the USA/Canada markets, it seems not unlikely
that Lucas might not have had one in production yet, and Tung-Sol may have
been the only supplier at first.
As some of you have probably already seen, it is listed in the XK120 pc as
C.5230 Flasher Unit (Tung-Sol 241/D), with C.5232 Mounting Bracket. No Lucas
number.
I have a Tung-Sol 241/D for my Mark V and it has screw terminals and a
separate clip mounting bracket similar to the grease gun clips.
I also have an unmarked but nearly identical flasher with an L-angle bracket
spot welded to the body and a BEES bolt in it, which I suppose is an
alternate version from Tung-Sol. I’m sorta sure this is the one that came
with the car when I got it in 1969. Even back then I was saving dead parts.
:wink:
The USA Mark V’s had a double filament bulb in the front sidelight and two
bulbs in the taillight. The wiring is separate wires not part of the main
wiring harness, indicating that it was an afterthought, not originally
planned in the harness design.
I am often amazed at how many UK and OZ Mark V’s and 120’s you see with
modern lights added on for turn signals that never look right, rather than
simply converting the original lights to the USA specification. Maybe they
just don’t know.

In URS SCHMID’s Volume 1 of XK120, he pictures two versions of Tung-Sol
switch; presumably the same two versions Rob? No picture of FL3 though.

But I agree, looks like Jaguar had to source Tung-Sol from USA in absence of
anything yet available from Lucas, with the FL3 their first and would appear
unreliable effort in about 1954 - just in time for late XK120s so equipped,
and from the start of XK140. Interesting change/upgrade in Wattage, maybe
the FL3 couldn’t reliable cope with the XK140 42 Watt load, but managed OK
with the XK120s (and Mark Vs ?) 36 Watt load.

Rob and Roger,

Take a look at the Tung-Sol Flasher in Ebay Item 120887841811.
This looks similar to the Flasher that Urs Schmid shows in Volume
One.

I’ve been trying to decipher the electrical rating/capacity shown
on the Tung-Sol box: ‘‘For 2 21 C.P. 12 V Lamps.’’ I’m wondering if
C.P. stands for candle power. If that’s the case, then the Tung-
Sol flasher may have had less electrical capacity than the Lucas
Fl3 Flasher.

I’ve checked the flasher on my November 1953 XK120. Some time in
the past, the original flasher was replaced with a Lucas FL5. From
what Roger indicates, the FL3 flasher was available by August 1953,
so my car could have originally been equipped with the Lucas FL3.
Was the FL3 Flasher the same shape, size, and style as the FL5
Flasher?

In reply to a message from Mike Balch sent Thu 12 Apr 2012:

Yep, that’s the one I have, same bracket too. I’ll look
tonight to see if mine has a patent number.

The patent application was filed May 18 1949 by Philip
Sitzer and granted May 19 1953, #2639345 assigned to
Tung-Sol Corp.
It relates back to two other US patents for flashers by
Joseph Schmidinger dated 1937 but not assigned to anybody.
So I begin to suspect Lucas bought a license from Tung-Sol
to produce it in the UK.

A flasher with spade connection terminals patent 2822444 was
filed in 1956 by Signal-Stat Corp.

Lucas has a US patent 3400346 filed in 1966. This one still
has screw terminals but has an angle bracket. I did not find
any previous Lucas patents.

Candle power is archaic (defined by a whale oil candle) and
has been replaced by candela, which is defined by the
luminous intensity of a blackbody with a certain area at
temperature and pressure, or converts to a lumen per
steradian. Not really directly convertible to watts (joules
per second), and probably too difficult for the general
public to get their head around, so for marketing they may
have used candle power.–

In reply to a message from Rob Reilly sent Thu 12 Apr 2012:

The flasher I’ve had on my 1950 Mark V all these years has
Tung-Sol P241D 12 Volts Pat. No. 2103276 stenciled on it. It
is made with an all aluminum body and a separate clip.

The one removed from the car about 1970 is unmarked and the
main body is steel with an aluminum ring crimped over the
insulator base and a bracket spot welded on the tail end,
and appears to be the same as in Urs Schmid’s XK120 Anatomie
book page 177 photo 3.

The internal construction is identical for both and conforms
to the patent drawings. This patent owned by Joseph
Schmidinger is dated 28 Dec 1937. So I am fairly certain
that Tung-Sol was making at least 2 versions of this flasher
and either would be correct for the period 1938-1953 up to
the granting of the next patent, which is #2639345.

One of the flashers in Urs Schmid’s book page 178 is a model
P241D patent #2639345, and the date of patent 2639345 is 19
May 1953, so this one would seem to be correct for the
period beginning about June 1953 up to the time Lucas began
supplying to Jaguar. The internal construction is similar to
the previous versions.

I have a Lucas F5 dated 4-56 which I took apart and I find
the internal construction is identical with the Tung-Sol
P241D, so it would appear that Lucas must have bought a
license from Tung-Sol.

The other Tung-Sol flasher model 534 pictured in Urs’s book
has patent 2761931 which was granted 4 Sept 1956, so this
one cannot be correct for XK120. It is an improved design
also by Joseph Schmidinger.

There was some competitive flasher design work going on in
this period by Tung-Sol Corp. and their competitor
Signal-Stat Corp. One James Welsh left Tung-Sol in 1952 to
go to Signal-Stat, then left in 1959 to form a company with
his wife’s money called Welflash to make flashers.
Schmidinger and Tung-Sol filed a lawsuit against him for
patent infringement in 1967 and won. So if any of you have a
Welflash it is either illegal or may be a valuable artifact.

The terminals are marked:
X = hot power
L = load, to the L/R switch for two signal lamps
P = pilot, the instrument panel lamp

Rob,

My SB112 is dated:- October, 1952.

There were more than the one “Master” for these type-written/roneod Service
Bulletins, with the original Factory ones seemingly retyped/redone by JCNA
for distribution within North America, with the occasional deliberate
modification - such as deleting GBP prices and substituting (US) $ prices,
along with the regular US spelling where it differed from English spelling,
so not inconceivable that the odd date was accidentally omitted.

Not first hand, but unresearched guess, is I thought it was only the USA -
maybe all North America (inc Canada and Mexico) that had flashing indicators
fitted to late XK120s. Wasn’t until XK140 introduced that RHD XKs and
European LHD XKs got Flashing Indicators - and even then, very first XK140
had a different flashing-lamp fitted to the normally seen/known
XK140/XK150/Mark 2 front flashing lamp unit.

But as you say - in 1953/54 probably a lot easier for JCNA to source
Tung-Sol units locally in USA rather than Jaguar import them from USA, but I
dare say, the real reason was Jaguar was probably madly trying to source the
LUCAS FL3 unit and would have fitted them as soon as Lucas could supply,
with that leaving it up to JCNA to keep sourcing/fitting Tung-Sol units to
XK120s that arrived without Lucas unit already fitted - and why wouldn’t
you.

In reply to a message from Rob Reilly sent Fri 13 Apr 2012:

Hey, how about this note in Service Bulletin #112, undated but
probably around Nov '52.

‘‘Owing to shortage of supplies Tung-Sol unit part number 241D is
not included for certain countries, and it is the responsibility of
the Distributor to ensure that the unit is obtained locally and
fitted prior to delivery.’’

I wonder which countries? I suppose the USA since it would be easy
to obtain here.
