[Healeys] Main beam warning light

Well, thank you all for your replies.

I don't normally put much stock in the Clausager book, except for colour
pictures. However, I did find this which does help:-"Blah blah.At the bottom
of the speedometer was a high beam warning lamp, originally red but changed
to blue on some export cars from chassis 14171 on the 3000 MarkII".

Now, bearing in mind that the UK calibration people seem to want to take
months to do a speedo, I bought a decent-looking but non-functional unit
from Michael. Hence the speedo came from over the pond or maybe somewhere
even more exotic..Which may relate to the "some exports" bit??

One last question, actually two:-

1.	How easy is to get the little lamp thing out of the dial so that I
can swap my red for blue?
2.	With regard to my tacho, the red light has always been practically
invisible. I'm pretty sure that, back in the dim distant past (could be 20+
years), I put a piece of red plastic into an otherwise empty hole. (100%
intact except for the red bit). The guy at Speedograph-Richfield said that
the red was just something cut from a piece of red acetate. Is that so?
Seems hard to imagine how...

Any ideas?

Hi Simon:


My BT7 tri-carb, which is very close to yours in serial number from previous
conversations, has a blue high beam warning light (red ignition warning
light). I doubt that the UK / European cars were different - no indication
of different speedo / tach part numbers in the original parts books, but
perhaps another UK lister could chime in here and verify.  I suspect that
it's a typo in the Anderson Moment book.  The referral to 'ratio' is the
number that insures that the speedo head is is properly matched to the
different rear axle ratios that were used during the 6 cyl production - up
to the BJ8, which went to black instrument faces, and an electronic tach, as
Bob indicates.

We're looking at a MkII BT7 here....

So, my speedo has just come back from calibration and, comparing it to the
one still in the car I see that the former has a RED "Main beam warning
light" whereas the latter, still in the car, has a BLUE one. 

The bible, Anderson & Moment, is confused and confusing on the topic. Page
104:- "..next was the speedometer, with a number on its face indicating its
ratio, and which included a mileage meter, resettable odometer, and the RED
"ignition" (discharging) warning light....On the right was the tachometer
with a number on the face indicating the ratio, and incorporating the RED
high-beam warning light." 

Now, unless that all refers to LHD cars, that's just a muddle. Doubtless
subject to subsequent corrections.

However, it leaves me confused as to which colour is correct.
