Works great. Completely silent.
Completely silent. Flashes faster than my old flasher which was a bit slow. If you still hear a clicking, make sure you are replacing the right flasher. You might have one for turn signals and one for hazard lights.

Great All LED Golf Cart/UTV Replacement
Worked Excellent. I needed one for a Golf Cart that has all LED lights. Old flasher was failing causing dim turn signals. Plugged right in and immediately started working well with bright signals and normal flash rate. I ordered one locally that was said to be for LED and didn’t work. Ordered a few others on Amazon and didn’t work either but this one was the Winner. Highly recommend for Golf Cart/UTV with all LED.

This was the solution
I can't give 5 stars but this LED turn signal flasher solved the problem! I highly recommend this product. It's a high quality product for sure and perfect for vintage bikes.

You may have to cross the connection for this to work with LED
This flasher relay works with LED bulbs. But on my (but maybe not on others') 69 mustang the wires needed to be crossed for it to work. I guess, in the original flasher relay, bi-metal switch inside works regardless of which way the current may run. However, in this flasher relay, the IC inside used to detect the lower current through LED bulbs does not work properly if the load and hot wires are not connected properly. Since the 69 Mustang comes with an L-shaped connector that fits on the flasher relay only in one way, I assumed that the load and hot wires will connect correctly to the relay. My guess is that the LED flashers that I purchased previously and did not work would have worked, if I had crossed the wires too. I wonder also if some old cars with L-shaped connectors have the wire arrangement that works with these LED flasher relays without crossing the wires. In any case, if it does not work, I would suggest crossing the wires.

Works great, doesn't "click"
Bought two of these for my 1972 AMC Gremlin. Standard plug-n-play, worked great in my car. For hazard lights, it keeps you sane. However, I like to know when my turn signals are flashing without having to look at the dashboard. These are solid state with no extra "clicky" feature so if you are confident in the inner workings of your car, great. I like the extra assurance and I just like the click sound.

Decent flasher relay for LED lighting
I ordered this as a replacement to another brand that said it was a LED capable flasher. This one works on my motorcycle as well as my old car I just converted. It fit the plug and the blinkers are nice and even timing for the flashes. It appears to be well sealed. It's compatible with the older GL500, a SYM Symba and a Plymouth Roadrunner, I'm happy with the purchase. It's also silent, which is good, in my opinion.

Do not use for LED conversion bulbs.
Did NOT work with LED lamps without adding load resistors. Signals just stayed on without flashing just like original flasher using 1157 conversion LED's.

No funcionó
El producto llegó bien cerrada y a tiempo. Al instalarlo, law luces no encendian. Verifiqué las conexiones de acuerdo al diagrama y todo estaba bien, pero seguir sin funcionar... se que el producto es bueno, y realizaré una nueva compra, pero creo que me tocó la mala suerte de ser el porcebtaje de error
