Topic: Light bulb size


flatheadfan    -- 01-16-2016 @ 5:19 PM
 

I tied this question on Fordbarn and had a limited response suggesting a LED bulb instead of a conventional bulb.

I have looked just about everywhere for the correct light bulb size used in a '35-'37 glove box clock. I can find no references in any Ford publications. A #51 bulb fits but is very, very dim. A #55 is too big. I am using 16g wiring and have a good ground.

If a LED bulb would work any anyone know of a size that would physically match a #51?

Thanks

Tom

  I do not believe they have 6v LEDs ,but if you go on tube there are videos on how to add the right resistor . Led do come in physically different sizes

  First I would check to see that you are getting at least 6 volts to the bulb, with the lights on.

Next, I would make sure that I had a fresh bulb, incandescent bulbs do get dimmer as they are used.

Next clean the white background in the clock housing or repaint it with a bright white paint. I used a 1994 Buick Bright White on my instrument cluster.

Here is a site that has the led replacement for the 51 bulb, but I don't believe that it will be much brighter than a new bulb.

  I have tried those LED bulbs and they are VERY directional. Best to get the original style bulb working right.

  Grounding, grounding, grounding. A poor ground is usually the source of lights not burning brightly. Run an extra wire from the clock housing to a clean ground source. The glove box clock tends to be isolated somewhat from a good ground source. You could also solder an extra wire to the metal bulb socket and run that wire to a good ground source.
