3 Volt Flashing Bulb Lights

  • Do not use a 9 volt battery with these 3 volt lights.
    Even if you plan to use several 3 volt LEDs together they will be destroyed by a 9 volt battery. These LEDs can only be used on a 3 volt power source 
  • If you need LEDs for a 9 volt /12 volt battery, we have them here: LEDs for 9 volt battery

Running Solid and Flashing LEDs Together on a Coin Cell Battery?

  • Solid and Flashing LEDs can NOT be run on the same coin cell battery as the flash will “carryover” and cause any solid LEDs to flicker along
  • Solid and flash can run together happily with bigger batteries.  Consider the AA holder/switch it has no carryover.

Don't Forget Hook-Up wire! Add extra wire to your LEDs with 25ft spools at just $3.00. 

All of our LEDs come with a 2 year warranty!
