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!

Cody McCary
Great lights, fast shipping!

I got the 3v flashing red led for a police robot build and they worked great! Only thing was they were a tad bit bigger than the micro LEDs I’m used to working with but I was able to squeeze them where I needed and they tuned out great!

Perfect Fit

The 3mm bulbs fit perfectly into the holes replacing the plastic fake bulbs provided with the model kit providing port, starboard and running lights. Looks great.
