RS does carry a couple mini lamps with 50 mA and 60 mA ratings for those that want brighter. I had picked those up also, but now do not know the P/Ns.

Good work, Cody!!

Thanks Travis. I might have sniffed some lead but I'm sure I'll be okay. Lead sure evaporate fast when you touch it with a iron...

Is your display not as bright in the daylight? I just want to make sure i'm not the only one

the pic of the candidates on the left is a 60ma, I might throw one in to test.

yes, mine is a little dimmer, I am going to try the other lamp in my pics.

Keep me updated on which one is the brightest.

OK I just tried several bulbs and the brightest and best looking was a # 70 rated at 150 mA.
Here is a link to a page that shows a #73 and #74 lamps like used in GM dashboards.

I tried a 73, 74 and a 70 and all three are bright enough to back light the display in sunlight.
Just bend the leads 90* to the body of the bulb drop it in the hole and solder.

#37 = 80mA.
#73 = 80mA
#74 = 100mA
#70 = 150mA

The actual amp draw will vary from one lot of bulbs to the next.
I think wally-world sells one or two of these number bulbs (lamps).

Now if someone who is good with a camera like Sonoma_zr2 will give this a try.
I never thought about soldering the bulb in till he posted the picture on previous page.
