Alfa,
LOTS of different bulbs ALL over the AS Classic moho. 1157's in the tail-lights, 1156 in the spots above sofa, T10's for clearance lights. These are all incandescent bulb numbers though.
I've ordered quite a few different bulbs in the past 2 weeks. Since they are all coming from Hong Kong, I'll be lucky if I get them before Christmas, much less before the New Year.
I'll post my results when they arrive.
Thanks, Derek

I replaced front and rear clearance lights with self contained LED units that I got at the truck supply store. I think the cost was $5-$6 a piece. The nice thing about it was getting all new red/orange plastic lenses AND LEDs all in one shot. A few of the original lenses were cracked, chipped, stuck on with silicone, or missing altogether, so it solved a bunch of problems and they look great.

I gotta ask...
Not one comment, or opinion on my "LED vs Incandecent" test..
Was my F-stop and shutter speed test too much to grasp, or just plain too "Nutty Professor"?

This always puzzled me as well, but I'll take a shot at explaining it.

Try to think of letting light into a camera to create an image or film exposure as you would think of opening a window to let some air into a room.

Shutter speed = how quickly did you open and then slam closed the window? If, say there was a strong wind blowing (think of air as light), then you got all the ventilation you needed pretty quickly.

F-stop = how far open did you actually swing out the window to get the amount of ventilation you needed? Wide open, or only partially open?

You can see that that getting a desired result would be a combination of these two factors. Hope that helps.

Derek,

I got them at a local store called East Coast Truck, but it's not be a national chain.
Just google "led truck marker light" and you should come up with the same thing. A decent Truck Stop would probably have them.

Charly.

Key,

Maybe just a tad bit "Nutty professor-ish".

But as I've said before, I think of you as more of a Mad Scientist!

And furthermore, I'm not surprised that you speak more Italian that the rest of us either. I refrained from commenting on your language proficiency in a different thread for fear that my remark might have been misconstrued my the gentleman that just took delivery of his moho overseas.

Ciao,

Charly.

That was great Charly!

I am no expert and was looking for an laymans explaination of the F-Stop thing.... and found nothing more than more silly stuff to put in my brimming head!

Did you know that:
"In optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture[1]) of an optical system expresses the diameter of the entrance pupil in terms of the focal length of the lens; in simpler terms, the f-number is the focal length divided by the "effective" aperture diameter. It is a dimensionless number that is a quantitative measure of lens speed, an important concept in photography."



Now, one thing that I did find that is interesting....

"Increasing f-numbers, in one-stop increments; each aperture has half the light gathering area of the previous one."

Now....
In one of my tests, with the 5W tail lamp lit, the stock bulb and unpainted can read F2.8, and the Chrome painted + LED was F4.0, with the same shutter speed...
If, based on the diagram and statement above from Wikipedia, the "light Gathering area" of F4 is half of F2.8... I guess that means that the LED + Chrome Can is Twice as bright!


As for my somewhat rusty Italian...
I lived in Torino for nearly 5 years, and then again in Tuscany, working for Piaggio for 2 years on and off.... Still wish I had bought a Scooter...
I like to say I speak a lot of Italian... BADLY!

Ma, che credo... sono un poccino pazzo!

First Lucas "Lord of Darkness" and now Marelli, his evil Italian cousin, I'm starting to understand your Airstream affinity.
