3157 3057 3357 4157 Turn Signal White Yellow Amber Switchback Led Light Bulbs 22 SMD with Projector, for Standard Socket, Not CK, Pair of 2

“Installed these LED switchbacks on my truck and I’m really impressed. The white DRL/running light is bright and clean-looking, and the amber turn signal is super noticeable. The switchback feature works exactly like it should with a smooth change from white to amber when signaling. Installation was straightforward and they fit perfectly. Much brighter than stock bulbs and definitely modernized the look of my vehicle. I’ve had them installed for a while now with no flickering or issues. Would definitely buy again.”

These work great for my 03 F-150. I had to install load resistor to keep them from hyper-flashing. They work as advertised!

Super easy to install, they are very bright and do exactly as advertised. I’ve had them for maybe a year now and they show no signs of giving up. They DO NOT come with a resistor to eliminate hyper flash. So just expect that. But for the price I’d buy them again

Work great and are super bright but they are a little darker then what i expected just by a little not to much but was expecting pure white led over all good and bright leds

Lights are bright. The only thing I didn’t like is that every time I activate my turn signals is that they blink too fast instead of normal blinking.

UPDATE: Ive had these in for over a year and they're still as bright as the day i istalled them!! No complaints and not one issue since installation... I'm actually pretty surprised at how well made these are and how good they still look!! I bought these switchbacks around 11-12 noon and had them delivered the very same day around 4ish. The lights are intensely bright, so much so that I believe that they might be brighter than my low beams. The color on them are great as well, they're a little more or the blueish hue than my Low beams which are 6000k so that leads me to believe they are 6500k. All in all for the price you can't beat them especially receiving them the same day.....time will only tell how they hold up but I would certainly purchase them again (and will) and highly recommend 👍

Super bright

These are really cool bulbs. I love how they work and they’re very bright, but this set lasted a year and 4 months. I bought a pair in November of 2024 and it’s now March 2026. Great while they last, but these are both flickering now which could cause me to get pulled over. I replaced them with another set of white LED lights for now (all I had on hand) until I can find another pair of switchbacks.

This is the 3rd set of bulbs I've ordered. In my daily driver they last a good couple years before one will start intermittently flashing. I will order them again in a couple years, and have recommended them to all my friends.

The replacement bulbs are ideal, offering white running lights, and yellow signal lights.

Worked great

2002 Escalade. The flash pattern is totally off on these. Not a hyper flash issue as I have resistors in place. They do not cycle properly when flashing amber. Out of the 3 sets I ordered. I bulb was toast out of the box, one bulb is now flickering. The third set that came are white only, as in, they aren’t switch back bulbs. With the wiring mods I made, I have two DRL housings on each side that double as my signals. I swapped out these garbage bulbs for better ones a friend had laying around on one side of my truck. The borrows ones work perfect. Flash patterns is right. They turn on no matter if the DRLs are activated or if the head lights turn on. They’re perfect. These ones though are all over. Just don’t waste your money.
