Extremely Bright 1157 2057 2357 7528 2057A 2357A 1157A BAY15D P21/5W Switchback LED Bulbs White/Yellow 3030 Chipsets with Projector for Turn Signal Lights (Pack of 2)

The resistor wires should be longer. And should come with screws. But they worked great otherwise.

Some times the amber light change to white light when I make turns.

I bought these 2 times first time was back in July of 2020 no issues worked phenomenal. Lasted about 1 year and half they went out around December of 2021. Decided I would order them again, this time they didn’t even last 3 months bought them In January and both are out. Overall they’re really bright and seemed good the first time. Not sure what happened the second time, maybe different parts were used.

These actually function better than most other switchbacks. When your turn signal is on they only blink amber, then fade back to white when not turning. Alot of other switchbacks will blink amber, white, amber, white the whole time your signal is on which in my opinion looks cheap. These do not do that. When turning they only blink amber, no white until you're done turning.I've had good luck with most Antline LED bulbs over the last 4 or 5 years.

Overall, these lights work as expected, no surprised there. Durability felt nice and the LED chips appeared to be of quality. I really would have liked the white LED chips to have a higher Lumen rating, but for $16.99, I am not expecting much in the realm of bright light output. Again, they are fairly bright, though. Coupled with my LED H13 and 5202 fog light bulbs, it is a wall of white light coming down the road. Most people probably hate it, but I like it. It's a white vehicle with bright white light. It just looks right.

I had to file down the bottom part of the light when I first got it in order for it to make the connection to the pickup and work. I just used the sidewalk and rubbed the bottom of the light on the level concrete surface until the metal connectors were able to clear the plastic and connect to the ones in my vehicle and ultimately make the light work. The bulb on the left side is the original new condition where it wouldn't work for me and the bulb on the right you can see at the bottom that I filed the plastic part down, I had forgotten to put this in so I added it today 08/14/19, hope this helps someone. These have been in my GMC for 2 months now. They've worked great so far. I'll update if anything changes. In my headlight housing its "Opt7s, 7 months old now "at the top for my regular/daytime running lights, a sealight for the brights which are practically never used and these for my turn signals.

I bought the 3157 amber/white switchback LEDs to replace another brand switchback that was having problems. These were a lot less expensive than the other brand and work great. I can't talk about longevity yet. My Toyota uses "CK" 3157 sockets that are wired up a bit different than a standard 3157 socket. The CK socket doesn't have as many switchback bulbs made for it. I noticed the description on these switchbacks says it support both CK and non-CK sockets. They work great. Note: If your sockets only support turn signal (as mine did) you have to run 12V to your socket to light up the white LEDs for running lights. I had already done that for the previous switchbacks.Longevity update: Of the two switchback bulbs, one lost (no longer light) a small grouping of white LEDs at two years. I consider this good as I had much more pricey switchback bulbs that had sections die sooner. They are also in a harsh environment (always on when the engine is on and no air flow in the enclosed lens).

Easy to install (if you have the room) and they work. Only issue is the connectors, which were kinda flimsy. The resistors were solid and appeared well made
