I have the blue LED mod and I bought mine from Radio Shack. I bought the
lower intensity of the two they have as I don't want the cabin to be lit
brightly at night.
Here are the possible reasons your's don't work:
1) I assumed you check the polarity. Flip the LED 180 degree around and
if it still does not work try 2)
2) The driver in the monitor panel intends to drive a few tenths of
milliamps. There is a current limiting resistor which you can find by
tracing the circuit board trace from the LED. You may need to adjust the
value so the LED does not draw excessive current. I set mine to about
40mA and it is plenty bright.
3) From what I remember the Radio Shake blue LED has built in current
limit resistor so it can opperate from 5V. You may have to reduce the
current limit resistor on the monitor panel or short across it. Please
check carefully before you shorting the resistor.
Hope this help.

hey all,
my LED green light to indicate my propane pilot is burning is very dim
at best. so i went to radio shack today to find a replacement. i found
a cool blue led that looks identical to the green stcok bulb. however
when i installed it the LED replcemetn would not work. i then
reinstalled the green buldb and tyhat still works. i tried a second
blue LED (i bought 2 just incase...) and that would not work either.
what is the right type of bulb to work here? it seems like a low
voltage circuit board and most any bulbs should work. does anyone have
better info, i really liked the blue bulb and would like to go with
that. the bulb i purchased at radio shack is a high out put 5mm
infrared LED, output is 16mW min. forward voltage is 1.2v, forward
current is 100mA. are these not correct for the westy sicuit board? TIA
for any inout jason 87 syncro westy
