Lazy question on the Bright6
Has anyone worked out the value of resistor needed to reduce the high-beam warning light to a level that doesn't make the eyes water at
night?
I could undo my dash and faff around for a few hours, trying to find the correct value... but if someone else has already made the effort... 
David
BTW: I don't care about the indicators - I keep leaving them on anyway, so the brighter the better! Same for the warning lights - they only
come on in case of emergency, so brightness is good.

No idea about the resistor value but what I have noticed is that if you wire it up 'right' you can make smoke come out of it and then have
half the LEDs stop working!
Must be based on an early development model by 'Q' for James Bond.
Cheers,
James
P.S.
David,
What about fitting the variable resistor from a Sierra?

you mean like a dash lights dimmer switch

I guess that a variable resistor is the easiest way to fix the problem! I could just tuck it out of sight behind the dash. Reliability would be the
only issue - vibration and damp air aren't good for variable pots.
The alternative would be some clever electronics (i.e. a transistor and a few resistors fed from the lighting circuit) but life's too short.

im not sure, but i didnt think you could use LEDs with resistors? someone correct me...

What about some kind of plastic filter/sunglasses material type thing for a light reducing effect

the dash lights would be fine, but everything else would be a dark blur

David,
You can buy a dimming kit for it for £1.99 from the manufacturers.
Probably less effort than fabircating something!
Cheers,
James

It's just that I have a box full of assorted resistors at home...
...if I have the right value then all it will cost me is some spare time.

Try a few in series. Can't hurt owt

LATE UPDATE!
I had a e-mail from Lightning Looms a short time ago...
"The value of resistor you can use is between 6k2 and 7k5 around 0.5W rating but this won't be visible in bright sunlight, but you can
wire a switch in parallel to the new resistor then you can adjust this for daytime and nightime driving."
I fitted a 6k2 and it's still bright (but at least now I can see down the road when I'm on full-beam!). If I get round to taking the dash
off again then I'll probably fit the 7k5. I can only just see the light in bright sunlight but, to be honest, I don't care when
it's sunny - when the sky's a bit more gloomy then the light's clearly visible.

mhhh
wy not use an auto dimmer?
use an var resitor called LDR...
then you should be able to fabricate...
an.. auto dimmer is light full brightness
is it dark minimum..
Tks

I thought about getting clever with electronics - then realised that it wasn't in the spirit of the car - as simple as possible.
The resistor cost me 0.7p in Maplins (I was too embarrased to buy just 1 resistor, so bought some other stuff as well!). I can see the lamp when I
need to, and don't care when I can't see it (bright daylight) 'cos I won't have my headlights on then anyway.

I assume you'll be attending the Tuesday night meetings David,
not the Sunday morning one's.
