Bob,
I am using an LR3 voltage regulator and a B&C 60 A alternator. Is it
acceptable to change out the supplied warning light for a red 12 volt led?
It would be in my direct line of sight so I do not think the lack of
blinking would be an issue. That is if the blinking is a function of the
light and not the regulator. Please let me know if there would be problems
with using an led and if it would blink. TIA Don VS

Yes, but the circuitry in the LR3 was designed
to drive incandescent bulbs. You'll need to
add some resistors to the LED circuit such that
the LED mimics the bulb. See:

The flasher is built into the LR3.

For a low voltage light you are unable to ignore I installed on of these Whelen stroble/flasters with my LR3 regular. Sits on the say, even a blind dog can see it when it goes off.
