We can also get the incandescent version from Onan, but please note that the incandescents will not last as long as the LEDs.  If you want the Onan original, please contact us.

NOTE: These will work on 22-28V AC OR DC - They are typically used on AC voltage in the Onan transfer switches, but when used on 24V DC power, polarity must be observed!

Contact us with questions!

The Cummins / Onan 0322-0137 indicator lamp fits many Onan OT transfer switches to indicate Emergency power is available.
