Quick Flash Strobe LED alternator

Regular price $16.50
  • In stock, ready to ship
  • Inventory on the way


The strobe quick flash alternator is excellent for diecast emergency vehicles such as police, fire, or other emergency services. Or use it in maintenance vehicles such as tow trucks, snow plows, maintenance of way vehicles. Or use it for airplanes.

The Quick Flash Alternator comes with our "Chip" sized LEDs pre-attached

There are three quick flashes on one side, then three on the other. 

Color Choices:

  • White
  • Blue
  • Yellow
  • Red
  • Red/Blue combination (not shown in video): the 3 LEDs on one side are red, and the 3 on the other are blue.


Each LED is on its own 8" wire, so the chips can be a maximum of 15" apart from each other. The magnet wire is fine enough, it should be easy enough to coil it out of the way for smaller models too.

This unit has a small circuit to control the LEDs, which measures 0.95in x 0.45in x 0.27in

Customization: Need something different?
We can customize this Strobe circuit by swapping out the LED with any LED color or size we carry. Choose the "custom color/size" option. Please list what lights should be on EACH side so we can build your custom circuit.

Very nice kit, but they only have big batterys

I ordered this for a 1:64 greenlight car. when I got it and tested it, the battery was about the size of the car. they gave me a 9V battery and I didn't know I had to specify what type of battery. The kit is great though.

Hi Luke I am sorry the battery turned out to be too big! Yes, our current circuit needs 9 volt. But I wish you had contacted us before you placed this order because we can make custom alternators and we have made several for 3 volt. A coin cell is much smaller and might have been more workable for you! https://evandesigns.com/products/3v-coin-cell-holder-with-switch In general, it's best to reach out to us with concerns as we often answer!

Customer review

The order was great and easy to install. The only down side is that the order does not come with flash patterns . If you could include different types of flash patters that would be great!! Awesome product!

superior quality flashing LED's.

Absolutely perfect for my ecto 1 bumper strobes. So easy to install. 3 led's on each side but only needed one of each. Taped up & hid the others without any fuss. Such fast delivery too. Will be buying more led's for my mods. A definite must for anyone doing mods who want an easy installation. Thank you so, so much Evan Designs.

Outstanding product backed by top-drawer service

Cannot say enough about this product and how Shelly and Dave support it. Have used it numerous times for diecast emergency vehicles, school buses, etc. And they happily custom-build whatever I can come up with. Always delivered quickly. Evan Designs is the best...thanks to Shelly and Dave!

Fast Service

Had custom navigation lights made for a helicopter. 1red & 1green on one side and 1 clear on the other. Fast service and great communication. 3mm are very bright. Thank you!!
