Simultaneous flash LEDs are a custom-made item.

What we have done is take 2 of our regular SMD LEDs and added them to the same flash circuit. The LEDs will be on 8" fine wire so they can be up to 15" or so inches apart

The listing is for TWO, THREE, or FOUR of the same color and same size LEDs. These synchronized LEDs will flash or flicker or breathe all together.

If you want different colors or sizes flashing, breathing, or flickering together, select the custom button above to tell us which colors you want to combine into your one circuit. ***

For the Flashing options, the same flash rate applies to all LEDs on the circuit. Below are the Flash Speeds

Fast  fast flash

Normal  normal flash

Slow  slow flash

We custom make these here on a per order basis so please allow a few extra days lead time for these to be made and sent.

LEDs for both toys and real cars.

These people have it all.I wish i knew about them when i was putting my street rod together.Now that i can't afford doing stuff like that,I play with toys that need special LED lights because the junk from China with all their fancy circuit boards just crap out too easy or fast and can't be fixed plus try to find replacement parts.These people are so nice to your with,their pricing is great,they ship fast and tracking is supplied instantly when shipped Oh and yes,items can be tracked right to your door not like the latest and the greats that the big rip off system and guys use today.Use them once and you'll be back.

Great service above and beyond

This was the most amazing product and service I have received in a while. Ordered Sunday online called Monday to ask if they could expedite, so amazing to be able to talk to someone. They went above and beyond. Even called back to verify something on the order. Product shipped same day. In addition the product was unbelievable and was even exceeded expectations
Thank you for your amazing product and service.

The Absolute Best!

Have used Evan Designs LEDs for over 10 years to ligiht and sell diecast vehicles for model train layouts. They are hands down the best in terms of product and service. These sync LEDs are outstanding for thiings like police and emergency vehicles especially because you can specify your own color and size combinations. Shipping is super fast. There is just no reason to shop anywhere else!

I am working on a car model I had in the early 80s. I was an EMT and provided my local community with my time and skills as needed. I wanted to add some realistic effects for my model. As soon as it is completed I will be uploading some pictures. Thanks for the service and support and getting my order out as fast as you did. I will be making additional purchases in the future.


I've never worked with LED's or circuits before but wanted to light a hobby project. This made it super easy and was exactly what I was looking for. Thanks!
