Dash lights
 

I just removed the dash light diffusers from a '50 instrument cluster and the glass diffusers are a dark lilac/purple, All I have ever seen in the past have been green. Has anyone else ever seen any that weren't green??

Re: Dash lights
 

Mine were dark purple. I removed them, and painted the bulbs green with model paint. Looks great and I can see the gauges at night.

Cecil,

Mine are the dark purple also. They let very little light through. I picked up a set on ebay just to inspect. They were very dark also. I shined an led pinlight from the back and they didn't let much light through either. I am told that these "filters" darken with age. I was also told that someone in the '49-'53 Club has been working on reproducing a replacement for these. Perhaps John Treadway in Lima, OH can "shed some light" on this. I would be interested also.

Merry Christmas,
Pat

Cecil-

I can't speak directly to a '50 but on my '51 I had a similar problem. More unnerving was I couldn't see anything at night. Out of frustration I pulled the speedo cluster removed the filters and painted everything inside that could not be seen from the outside white. Result- no problems seeing anything at night! At my age my poor eyes need all the help they can get! :)

Re: Dash lights
 

Ken, You are correct....John doesn't do 'puters! He is in our regional V8 club. I will give him a call later. Thanks, Pat

Re: Dash lights
 

What I have is a spare instrument cluster that I am messing around with. I already took the diffusers out of the 2 '50 Fords that are in my garage and they were both green. I put green rubber covers on my bulbs and they are GREAT!! I just hadn't seen any that weren't green before and raised the question.

Re: Dash lights
 

What did you use for "green rubber covers", and do you think the heat from the bulb will last very long? :eek:

Re: Dash lights
 

Tell him i hope he dosen't get this snow storm comming his and yours way. We try to vend next to each other at meets. ken ct. Merry xmas Pat.:)

Re: Dash lights
 

Interstate truck centers, Flying J ,TA truck stops etc etc. they have diff colored covers.ken ct.:)

Re: Dash lights
 

Lawson, The MCI motor coaches in the 70's into the 90's used these coverson all their instrument lighting, probably as many as 20-25 bulbs in different colors depending upon whether they wanted green, amber or red and they work great, no problem with bulb life. I've had them on my '50 Ford for probably 10,000 miles.

Check out the link. It is a PDF of the lighting boot catalog.
http://apmhexseal.com/catalog_pdfs/apm_sk-100.pdf
AMP Hexseal makes colored boots for instrument lighting. These are used extensively in aircraft instuments. If they do not sell direct they can point you to someone who will.

Hi all; I read an article in the V8 Times, I believe, that explained thst some years of 5o's Fords used a 'Radon' instrument paint that faded with age. Your solutions seem right on. Newc

Re: Dash lights
 

Cecil, I just spoke with John Treadway (Lima, OH) about these filters. He indicated that all he as seen are the purple color. But, he did say that there are special green colored bulbs for the turn signal holes in the dash cluster. Have you ever held a light bulb, or any light, directly at the instrument cluster at night? You'll notice that the numerals really glow after removing the light source. According to the '49-'51 repair manual, this was call the "black light" effect used only on the '49 and '50 models. The '51 models used direct light.

Ken, I just spoke with John. He said you guys connected earlier today. It's getting real windy right now...trying to brew up something!

Merry Christmas to you & yours!

Re: Dash lights
 

Cecil, I just spoke with Steve Chapman in California about these filters. He has done a lot of research on these little guys and has written an article or two for mags. Anyway, he has indicated to me that these filters are indeed green to almost black. He has come up with a kit to replace these with a blue filter which he says gives off a nice light. I believe he has converted his car from 6V to 12V. It seems to me that you could just remove the filters and use direct light just like the '51. Or, use somekind of transparent paint to paint the bulbs as mentioned above to filter the light a little.

Re: Dash lights
 

The after glow is from the luminecsent paint that Ford used in this time period. It is similar to the luminecsent paint used on wrist watch hands. Many aircraft and military vehicles utilized this method for low light conditions. You could turn off the instrument lighting and still read the gauges for a while.
The colored boots I referenced are used to tune the lighting spectum of incandecent lamps to meet to the MIL specs for instrumentation lighting. These are not expensive and will allow very nice uniform dash lighting automotive applications.

Re: Dash lights
 

You can remove the filters and then color your bulbs with a felt tip pen. I did this on some turn signal bulbs some years ago.

Re: Dash lights
 

Yes, that works to a point. It boils down to "How often is it lit?" In the aircraft applications that I am familiar with they are lit whenever the aircraft is running. The felt tip solvent based inks are best for longevity. It was common to use Sharpie brand pens to do the fine color tuning. In the Aircraft application the pens were used in addition to the colored boots. For a car instument panel that method will work until a lamp burns out. The advantage of a colored boot is it can be removed and reinstalled on a new lamp at replacement time.
