RUXIFEYSequential Switchback Side Mirror Marker Lights 3-Row LED Turn Signals Compatible with Ford F250 F350 F450 Super Duty 2008-2016

Fit prefect. Easy install and work great. Nice and bright

Fast delivery. Clear instructions. Easy to install. However, you probably should replace the "O" ring seals where it plugs in. My old one, from a 2016 truck, were dry and cracked and could have let water get inside during rain or car wash.... so I replaced them too. Installation was very simple and they work and look great!

I like the white running light that does the switch back to yellow for turn signals. Swapped them out in under 10mins.

They look an work great only thing is that I thought I had them on the wrong side but I don’t. They do not sit flush an closed the a stock one should. I only worry because of water getting in behind the mirror . An in the winter if water does an it freezes not sure if the heated mirror will be enough to unfreeze it all.

I really wish these had worked properly! They looked nice, fit nice, and were good and bright.... then i cut on the blinkers. They just went haywire. You never knew what you were going to get when you cut on the blinker. Sometimes they would add a white flash every third or fourth blink. Sometimes they would just stay white. Rarely would they flash as described. I reached out to the company, but they offered me no fix. They just told me to return them. That gets you a poor review.

Nice fit. Amber and white light depending on turn or door opening. It is as advertised.

They work perfect, all you have to do is use a wire brush in the bulb holder to remove any previous corrosion, then pack the light connectors with dielectric grease then kinda work it into the bulb holder connector. Then they work flawlessly. As of right now it’s been a few days and they’re fine. I’ll do an edit if they break or something happens

Works as described when the flashers are on, gets an intermittent white flash on the switchback when the turn signal on either side is on. Fits well and looks good otherwise but don’t expect it to work correctly all the time
