Headlight Bulbs

Having read and not wanting to jump into the thread "Hydro dipping headlight reflectors?" I have a question about the bulbs of the head lights.

I presently have the reflectors sold by Brattons that a lot of people have raved about. QUESTION? When installing the bulbs does the bigger/longer filament go to the top or bottom?
 
Strangely enough I would have thought just the opposite.
The LARGE filament on the top and being the HIGH beam.

Thanks for the info Tom and I will change my tomorrow.
 
Yup Tom is right, think of the filament on one end of a teeter totter and the lens on the other with an invisible pivot point in between - filament moves down light goes up, filament goes up light goes down.
 
It can be a pain to remember. I have gotten in the habit of labeling my bulbs (and all my many spares) with TOP written in Sharpie on the base. Otherwise, whenever I take them apart I end up spending time trying to remember which way they go back in.

I have at least a couple old bulbs that have the TOP marked base from the factory.
 
The original 1110 bulbs 32-32 CP bulbs have two identical filaments (both are pointed), one is mounted slightly off-center (Low Beam). The off-center filament should be towards the top of the reflector when locked in place. As mentioned, these bulbs have the word "TOP" rubber-stamped on the lamp shell.

If you're using the modern 50-32 CP bulb, the thin flat filament goes on top, and heavier, pointed filament should be on bottom, at center of reflector.

I went back to using the 1110 32-32 CP bulbs, as they seem to last longer.
