DC 4.5-30V 10A Dual Output Alternating Flasher Module

Works as described. Great price for a flasher relay. Easy to wire up Good size Works on my crossing signal that I made

I used one of these on a vintage Denver Fire Dept display that I built. Unlike some electronic flashers that require an inverter, this works fine just using a battery charger. Plus flash rate is adjustable too.

This was just what I needed to have the ability to flash some additional lights on the front of my vehicle. While I opted to adjust the timing for each "side" to be identical, the ability to adjust each one independently is a great feature that I'm sure would be very useful for other applications. Installation of this module is very simple and the "common ground" design employed eliminates the need to run a dedicated ground to each lamp. Very pleased with this purchase and would recommend this to anyone needing a flasher module. (Please note in the video that the flasher module is controlling the lights in the front bumper area of the vehicle. The lights in the visor are sold separately and not controlled by this module)

I used this because the flasher would not work very well with my 03 Ford Expedition. This flasher let's you set the on time and the off times of the flash separate. The led on the unit is incredibly too bright and I covered it with electrical tape. Only con is that it doesn't have the clicking sound you normally get with a flasher. Since it is not bi-metal and is electronic.

Very easy to install. We needed a replacement flasher for our 1995 Hummer Brush Fire Truck and we had very little space for it so this was a welcome fix. We use it as a wig-wag style flasher.

Wired up two lights exactly as the chart shows. Both lights just lit up constant on. The unit did nothing other than pass power to both lights simultaneously. UPDATE Apparently the lights I was trying to hook up were wired backwards by the original maker. The red was negative and the black was positive. Once I fixed that the unit worked perfectly. Bonus that it has built in polarity protection.

This is an easy hookup for controlling rates of alternating lights

Works very well. Only complaint is when getting close to super fast a small turn changes either a lot or a little. Hard to sync up two of them together

Used this to alternate my Led landing and taxi lights on my Cessna for visibility and to avoid bird collisions. Have about 20 hrs on it so far, works great and it does not create any radio noise in my headset. I had to add diodes on each output so that it doesn't flash the taxi light when I turn the landing light on steady.

description précise et juste.

Bought this to use for my railroad lights and it worked perfectly
