These were great tbh. Bright and worked well! Purchased in April, but the passenger side burned out in July. A shame because I really liked them!There are a number of possible options to put LED turn signals in a car designed for conventional bulbs. If your car uses a turn signal relay, replacing it with an LED turn signal relay is likely the best route. If not, there are LED bulbs with built-in load balance. From reviews I've read, they tend to not last that long. They probably get hot from the load. Then you can get LED bulbs without load balance and use an external load resister. Sometimes you can get the load resister with connectors on each end making it plug 'n play. This is the only one I've seen where the load resister is external, but it is fully integrated. It also has a unique rubber mount. At least so far, seems good. The resister it comes with is physically pretty big so it should dissipate heat okay. Now, it is not as bright as some others. It has fewer LEDs on it compared to some other brands. But it is a lot brighter than conventional.Bought these back in June of 2021. They looked great and I was excited about them. A month or 2 ago I got an error message saying my left blinker was out and it would hyper flash. I was going to change them back to the stock ones, but once I got home and shut off the truck and restarted just to make sure, they worked again. A few weeks later It happened again to wear the driver side was hyper flashing again. If they work and keep working it would be a great deal. I thought it was the canbus, but once I started replacing them, i noticed both the plugs were corroding. Somce there is no way for the plug portion to go in the headlight assembly on a 2021 Chevy Colorado, the plugs started rusting. This might be preventable by putting bulb grease on the connection points, but with no way of covering them rusting is inevitable.had to buy 2 times. first time installing one of the lights didn’t work and blew one of my fuses, after i replaced the fuse the light didn’t work so i had to order more. when installed the 2nd time they worked perfectly.I know everyone says they are all easy to install But blinkers all need a Resisters. This is to stop hyper blinking. Installing a Resister on a light is a pain in the A. The resister is already installed on this LED. So.. much easier to install. The have been working great!Update: After a few months one signal has started failing intermittently.Easy to install, work quite well no hyper flash in my GMc Canyon. Time will tell but ill be ordering the rears soon.They were bright but honestly not as bright as I wanted them. Overall still a nice led bulbEasy and fast installation looks great 5 ? recommended2017 F150, the plug is correct but they bulbs blink(more like quickly FLASH) amber and throw in random white blinks.Not cool. Would like a refund and WORKING bulbs sent....... Get on it seller.
