Syneticusa3157 Error Free Canbus Dual Color Switchback LED Turn Signal Light Bulbs No Hyper Flash All in One Built In Resistors (Turn Signal-Amber and white alternate flash)

The product is great, fits as it should, and super easy to install without any complications. I had one bulb burn out, Contacted the seller and got a response to have the bulb replaced. Their response was super quick, and no strings attached. Just super simple.I recommend this product 1000%

These were installed in C5 Corvette with clear turn lenses. All the other bulbs would flash amber-white-amber so on. This set turns the bulb white and gives a driving light with parking lights on at stalk yet switches to amber for turn signal flash and then back to white when cancelled. Nice bright safe white DRL for C5 with clear lenses and look much better too.

I like that this product has a great (large) resistor to prevent "Hyper-flash". It has a dual color: white and amber, which give a new look when on "running" and flashing. I like it very much!

While the customer service was good the first time the product really doesn’t work. The light does strobe (hyper flashes mimicking emergency lights) which has caused me to get pulled over multiple times. It works as expected for a little while then suddenly it doesn’t.....I find this out when I see cherries in my rear view mirror. No longer an option to exchange or refund, guess I’m s.o.l.

Everything was great BUT I didn’t receive switch back dual color LEDs as I ordered and what the box states. Other than that they were easy to install, they fit inside my 2013 Ford Explorer and there was no error code or hyper flashing. I still recommend these!

Great product.Super bright nice fast flash from clear to amber when signaling. Turn signal definitely will have better noticability by other drivers. And I feel like they even added more light while driving at night while they are on as white clearance lights.

looks so clean with the led .. only flashes yellow/ amber when u put on turn signal.. rest of the time it's a bright white helping the head lights... no hyper flash.. worked great

Had to add extra resistors but got them to work on my 2012 Toyota Tundra. Lights off its still amber/ lights on its white then also with lights on and flasher on it blunks amber and white but definitely looks good as well as modern. Only thing that would make it any better is if it would just stay white with lights off, that's not the LEDs, it's just how Toyota has the DRLs wired up.

Put these in my new headlights in my 05 f150 and they look awesome the way they switch from clear park to amber signal light. Been working good for 3 weeks.
