2 Bulbs 3157 Type- Switchback Error-Free 2835 42-LED Turn Signal Light Bulbs White-Amber (3157/7443/1157) (3157, White/Amber)

I bought these to fit into my 2019 F250 Lariat, Sport edition. Trying to find the right bulb size was difficult and apparently I inferred it (incorrectly) as a 7443. Unfortunately, these don't fit directly. However, if you trim the side nubs on the plug (I used a dremel) and cut some of the rubber off the plug-in end, they will lock down in the socket and work fantastically! If you look at the second picture, you'll see the side-nub at the top of the picture. There is a second one on the bottom. In the last picture you can see indents in the rubber at the base of the light, I cut out material between these indents to make more indents.While I am not advocating the purchase of these bulbs for the purpose of modification, if you find yourself with them they can be made to work.I gave them 5 stars because the issue I had is not their fault, and they really do work nice. They match my 6000 color LED headlights when in marker light mode, then blink amber when the turn signal is activated.

Put these in my girl friends 2017 jeep patriot. While the install sucks because for the patriot you have to take the bumper off to install turn signals. The lights are awesome it makes the patriot look like a mini version of the new body style wrangles that have the lights in the fenders. These are bright. They honestly act like a second set of fog lights but angle the light out to the side of the jeep. There is a slight delay from the turn signal turning back to white after the turn signal is turned off but is not a big deal but worth mentioning.

I ordered these bulbs in May of 2019, Installed it on 2013 F150. My daytime Running lights on my f150 is amber, and would like to have all my lights turn white when my head lights are on. So these would do what I'd wanted to do. Easy to installed, works great for a couple weeks. It started with the passenger side DRL blinking amber when the vehicle is cold, and the turn signal is not on. It wasn't bad to be noticeable and now both driver and passenger side amber lights will go on/off intermittently, and is getting worse. Have to drive around with my headlights on so that the signal amber light won't flash as if I was turning. I'd checked the connections in my socket and it looks good, have good contacts. I'm thinking it have something to do with the signal board, some lose wiring in the systems or something. Can't return it because it's pass the return period. So my suggestion is that if you buy it and notice a flickering when is not suppose to, return it or get exchange it for new, as soon as possible.

I purchased a set and it took me longer to get them installed than I wanted. When I did install one of the lights did not blink and seemed to hyper flash. I wrote to the seller and they were quick to send another set. Today I finally got to get those installed and they must have been wired wrong because they flashed white only and I could not get the amber to work. Do not waste your time with these units look for better alternatives.

Just installed so no rating on Longevity. So far great LED replacement bulb. True switchback feature. Bright and easy to install. A little concerned on two wires directly on the resistor.

Tried on my 2017 Ford F-350. This truck you have to remove your grill and bracing just to change the bulbs. I got it all done and tested it everything worked great so I put it back together. Come to find out the switchback only works on the drivers side of the trucks off, not when the truck is running. Now I have ordered a second set to see if I got a bad bulb, but now have to spend 2 hours ripping the grill off again.

I bought these for my Tacoma they did light and fit well but the switch back did NOT work for my application werent as bright as expected

The lights work well and pretty bright. It was nice I did not have to install additional equipment to make them work. I can not speak to longevity as I have had them in only a couple months.
