Great product!
Switching from incandescent to led? This is what you might need to properly control all the lights. Great buy!

Quick fix
This quickly solved my problem of turn signals that wouldn't flash after I replaced the old incandescent bulbs with LEDs. The hardest part was finding the location of the old flasher under the dash of my classic car.

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.

Work Great!!!
Work perfectly, but if you happened t have one set of CANBUS led signal lights already, they won't work with a second set of regular LED signal light bulbs. Both sets need to be either CANBUS or no CANBUS

Appears to be a quality product
After receiving this flasher relay... I changed my mind about installing new LED lights on my truck. This relay appears to be a quality product, just not for my solution for upgraded headlights on my truck

Works as shown!
Works perfect with my LED turn signals, if you go from regular turn signals to LED turn signals this is perfect for mechanical turn signals!

Totally nonfunctional - Do Not Buy!
Bought 4 of these - none of them work - Took awhile to get around to installing them in my projects so I'm outside the return window but hopefully this review will save the next guy from buying these POS things

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
