Poor Design
It’s supposed to be a 3157 but 3157 also got the twist lock on it and it got a rubber grommet with a lip that’s a push in and you hit a bump it goes out a place but I learned that it has an amazing light outputRead full review...

3157 dual color led
Made with quality leds and a projector lens on the front facing end. Heavy gauge wire pins on base for solid contact.

Cool turn signals
It looks cool when you use the turn signal. It turns amber and white. Had a lot of compliments. Was a little worried about connecting the resistor to it but didn't have any problems. The components was pretty easy. Never had to add a resistor before but it turned out it wasn't difficult. So I have to say this is a very good product so far. We'll see how long it last.Read full review...

Very nice 1157 switchback bulbs
Installed them in my classic 1968 Camaro and the make it look like the car originally had DRL bulbs then go to back to Amber when signaling. Very nicely built aluminum assemblies also. Thanks, will be going directly to your website for my next set of led bulbs.Read full review...

Very loose in socket
Had major issues keeping these bulbs in factory socket. Incredibly loose, lights would be on sometimes. One day they’d be working other days 2/4 would be out. Had them fall out a few times into the headlight housing on an 07 Silverado, which is not easy to access. Had to take the whole grill and housing out more than once. Watch outRead full review...

Bulb function
These bulbs alternate from white to amber when the turn signal is on. I was under the impression that the white led's should go off during the time that the turn signal is on and then go back to white when the turn signal goes off. Not alternate because it gives the look of a flashing light. It kind of looks like a security guard coming down the road. But all in all they are OK. Read full review...

Great switch backs
These bulbs are really bright in both amber and white it's like a 6k white not too much blue in it. It was perfect for me. Comes with the resistors can't beat the price. Fit on my 2002 silverado turn signalsRead full review...

Modern technology.
It's amazing how technology has changed in a simple turn signal bulb over the years. The detail has changed dramatically from simple light bulbs to lighting devices.

Quick shipping, and the products look to be of decent quality. Will look great in my clear signal housings. Haven't installed due to vehicle using ground triggers to activate lark and turn. Need to wire in relays to flip polarity of my lights. Read full review...

best switchbacks
amazing product works perfect i have been using these on my family's and friends vehicles you do need resistors because they will make your vehicle turn signals flash faster than usual and on some vehicles they wont work without the resistors but besides that they are great i've bought about 10 pairs and only a single led went outRead full review...
