Alan, for just a few LEDs, there is a good variety and pricing
at Hosfelt electronics, 800-524-6464. They have 4 full size pages of them
for prices about 6 to 10 cents for standard red, 12 cents for standard green or
yellow. Also jumbo size and superbrights including blue and white for
about 89 cents to $4. We use 1000 ohms to operate them on 12 volts so
I would guess around 4000 oh, for 48. Start high and adjust down to get
about 20 milliamp current, but slightly different values may be required for
white and super-bright models.
Overall it is a good catalog of surplus stuff of good
quality. I can fax those pages to you if you need to order at once.
However if you need fewer than 10, I have a good assortment
red, yellow, and maybe some green spare in the workbench that I would be glad to
send you no charge.
Also: when you install the digital display on a Trace C-40 or
C-60, a 2-color LED is removed and discarded. save these and you can use
them next time you need a separate LED.

Subject: LEDs [RE-wrenches]
Anyone suggest their best source for colored LEDs
for signal apps? I need several red, yellow, and green LEDs for both indoor
and outdoor apps for "pump on" (green), "tank low" (yellow); "tank very low"
(red) -type signals. Will need resistors to operate at 48V. Your best sources
in the US, please?
