90650 Heavy Duty 12-Volt LED Flasher, 2 Terminals, 2-Pin LED Flasher, 12V, 20amps, Plastic Body – 1 Unit

Used these to make my LED taillights on my 1966 F100 work. Fit great and worked great! Easy to use. Little to no noise and you can even notice it from where I have it installed.

Works well in my 1984 motorhome. It had reversed polarity, but I have easy access to the leads behind the fuse panel, so I just switched them over, otherwise an adapter is available. The ground lead is a bit short, so it had to be extended. It flashes about 60% faster, than stock, but it is not detrimental. Works well with mixture of LEDs and incandescent bulbs and with LED bulbs on the reasonable end of the expense scale. Still produces the sweet relay click. Almost unrecognisable, that it is not mechanical sound. Excellent value, if it lasts.

This is a requirement if you intend to swap in LED lights into your old model lights. The c-10’s have the two prong fuse and the lights won’t work properly with the factory style. This with help remedy that if you purchased the lights and can’t seem to get them to function properly. Works great and it’s easy to install.

Works great when upgrading classic car to all LED lighting.Get the standard timing between pulses instead of the hyper fast LED flashing

Works Great!

added LEDs to my 39 chevy, very nice upgrade but impossible without this flasher unit

This one worked great on my Grom motorcycle. After trying a different adjustable 2-pin flasher and having bad results I was pleasantly surprised and glad. I think the added ground is the key because it doesn't just rely on through-current but has its own constant supply. The flash rate is perfect, just like stock blinkers. It does have a mechanical relay and makes a nice click sound. Would recommend!

I installed two of these flasher units on my wife's classic car. It took two, as the car has four-way flashers, and the turn-signals and flashers are on separate circuits. When I tested them, everything worked... for about five minutes, then they all stopped working.I installed another one of these on my own classic car (without the four-ways), and it is still working three weeks later. Looks like production quality is lacking.
