## Description

desertcart.com: DC 4.5-30V 10Amp Blinking Flasher Module, Normally Open : Automotive

Review: Perfect For Siren Control - Before I got my Federal Signal FC controller, I used to use these to control the on/off timing for my siren's motor when doing attack signal. Now, I use it to flash the solenoids on my mini sirens that need a 1/1 pulse timing. This little module is exactly what i needed, and is a great price. Also has two sscrew holes so you can mount it. I will be using those holes to mount it inside a cabinet along side a couple relays and a contactor for a homemade single motor 3 signal siren controller.
Review: Great blinker module, can replace a bimetallic flasher for using LED's - This module works great, I paired it up with Sequential Turn Signal modules and with this unit I can set the on and off time easily for the best sequential turn effect.

## Questions & Answers

**Q: what is the slowest rate of flashes per minute capable with this product?**
A: If you adjust the ON and OFF all 15S, per minute 2 cycles.

**Q: any idea if this works with a 5v ebike led headlight/tailight with a 1 amp rating? I need them both to flash**
A: Connect it first to a solid state relay (SSR) then connect relay output to your headlight, make sure the relay can handle enough output current to operate your headlight.

**Q: Is this waterproof?**
A: Will it work under water?  Probably not but for normal use on a vehicle it should be water resistant enough.  I have them mounted on the fenders of my tractor.

**Q: I purchased one but the instructions are in Chinese....are English instructions available?**

This module works great, I paired it up with Sequential Turn Signal modules and with this unit I can set the on and off time easily for the best sequential turn effect.

### ⭐⭐⭐⭐⭐ Solved my problem.
*by D***O on November 5, 2025*

I have 2 strobe warning lights that were not synchronized. After 3 to 4 cycles of the strobe pattern they flashed randomly. By interrupting the power for a blink of an eye every cycle that the lights go through, they stay synchronized. Thanks for a good product.
