Review on 🔦 ANTLINE Extremely Bright 3157 3057 3155 3457 4157 4057 Switchback LED Bulbs: White/Yellow 3030 Chipsets with Projector - Pack of 2: Turn Signal Lights by David Sokolov

I had to file off the bottom of the light when I first got it so it could connect to the pickup and work. I simply used the pavement and rubbed the underside of the light over a flat concrete surface until the metal connectors could scrape the plastic and connect to the connectors in my car and eventually get the light to work. The bulb on the left is original new condition, it wouldn't work on me and the bulb on the right you can see below. I filed the plastic piece that I forgot to put in, so I added it today. 19 hopefully this helps someone. They have been in my GMC for 2 months. They've worked great so far. I will update if anything changes. In my headlight housing "Opt7s that are 7 months old" above for my regular/daytime running lights, marine light for bright bulbs that are rarely used and these for my turn signals.
