iBrightstar Super Bright 3157 4157 3155 3457 Switchback LED Bulbs with Projector Replacement for Daytime Running Lights/DRL and Turn Signal Lights, White/Amber

These bulbs are so awesome, I’m convinced they were forged in the halls of Valhalla by a team of Norse gods who just wanted to make my turn signals cooler. The white is crisp, the amber is bold, and the switchback transition is smoother than my dad’s pickup line at the county fair. What I Like: • The brightness is no joke—these things shine like a mini supernova. • The amber-off-amber-off turn signal is way more noticeable than the old flicker-flicker nonsense. • Install? Plug and play. I had them in faster than it takes me to find a matching sock. • They actually look good. People have asked me what bulbs I’m using—and yes, I do feel cooler. What I Don’t Like: • Nothing, unless you count my other bulbs now feeling insecure about their performance. My Final Thoughts As long as iBrightstar keeps making these bulbs in sizes that fit my rides, I’ll keep buying them. They’re the kind of upgrade that makes you want to take the long way home… with your turn signal on, just to show ’em off.

Reverse lights super bright

I installed these in my 97 Corvette when I discovered the old lens assemblies needed replacement. He installation is simple plug and play. Due to the lower voltage draw you will need a load resistor to stop the hyper flash issue. I got one that is a simple plug and play that installs behind the knee pad in the dash. Those who have given a poor review due to hyper flashing, do not understand the electrical system in their vehicle. Hyper flashing is not a problem with the bulbs, this information is all over and easily accessible with just a little research. The lights are very bright and work perfectly in my Corvette. THe switchbacks are very cool, they are amber when in DRL mode, bright white, when switched to parking lights, then back to flashing amber when turn signals are activated. This simple upgrade brings your older Vette into current times and gives a much needed upgrade.

Purchased 3/12/24 died 4/1/2026, the switchback feature worked pretty good and are really bright. One of the lights lost all the white LED's for some reason but the orange lights do still work. Only really lasted around 2k hours according to my hour meter on my F350

Bright easy to install great value.

Still working

I have these in my sequoia and they works great with my resistors. No issues so far and I have had these lights for several months now. Very bright durable.

Bought in 2020 they worked great for 5 years just bought a replacement because the one side is flickering now the new ones do not fit the socket is too small it just wiggles around in the plug

I got these specifically for the "amber-off-amber-off" feature. All the regular (non-switchback) leds I've tried flashed "bright-dim-bright-dim" amber at night, but difference in brightness was way too subtle. It was really more like "bright-slightly brighter-bright-slightly brighter" amber. Now my new signal lights are highly visable and the white parking lights are a great looking bonus.

Me a encantado su funcionamiento, muy bien 👍🏼

Quedaron muy bien y alumbran de maravilla.
