AUXITO 3157 LED Bulb Turn Signal Amber Yellow Super Bright, 3056 3156 4057 4157 LED Light for Blinker Turn Signal Lights, Brake Tail Lights, Side Marker Light, Parking Light, Pack of 2ClimatePartner certified

Why did you pick this product vs others?:After over a decade, my 2011 vehicle was due for a little rear-end refresh—and the AUXITO 1157 Red LED Brake Bulbs delivered exactly that. Installation was plug-and-play, no drama, no tools, no cursing at the socket (for once). These things are bright—like “you’ll definitely see me stopping now” bright.The red hue is crisp and vivid, not that washed-out pink you sometimes get with cheap LEDs. And the instant-on response? Chef’s kiss. It’s a small upgrade that makes a big difference in both safety and style.Honestly, I didn’t realize how dim the old bulbs had gotten until I popped these in. It’s like my car got a little attitude adjustment—subtle, but confident.

Installed these LED bulbs for front parking/turn signal lights, to replace original bulbs in a classic 1956 Ford. Used these along with upgrading an original mechanical flasher to an electronic flasher. Bulbs, with electronic flasher, work perfectly as two-stage parking light and turn-signal flasher bulbs. They are easily 300% brighter than original bulbs. Huge safety improvement. And the bulbs fit and have a shape almost identical to the OEM, behind the clear lens. Be aware that they are a bright white, where original OEM bulbs output a more yellow/amber glow and look. So if you have clear lenses (versus colored lens) and prefer to keep the yellow/amber look, go for the amber bulbs over these white bulbs.

The light output of these bulbs is bright and even, thanks to the plastic lens around the LEDs.I like to listen to distant FM radio stations and thus, they are weaker signals and can easily be covered by local noise sources.This is one of the few LED replacement bulbs I tested that does NOT generate RFI (radio frequency interference) in the FM broadcast band!THANK YOU!

Seem bright

The value of this product is good. no flashing stable no blinking!

The media could not be loaded. Exactly what I needed. Bought this as a Bought this as an upgrade for the under hood Lamp to my 93 GMC Sierra. I can’t be happier with how bright it is making finding lost bolts or anything dropped into the engine bay a breeze to find.

Update 12/29/23 - These have already failed. As suspected, they're way overdriven and heat up too much. All of mine have failed in a manner of causing cross-talk between high/low circuits when hot as well as causing hyperflash that was otherwise never there. When they're cool, they work. When they're hot, they go into failure. I tested 4 pairs of these on a vehicle. They've been promptly removed and Sylvania ZEVO's reinstalled. The ZEVOs are the best. Go with that if your application can use a reflector firing LED.These things don't seem too bad right off the bat.Let's get down to more specifics of pros and cons.First, let's start with the cons. The issue I have with these is just like I have with many offshore LED retrofit "bulbs." That issue? The overly high brightness. Wait, isn't brightness a good thing? Well, yes and no. It is good to be seen, whether it's for indicating the direction you wish to go, whether you're stopping or slowing down, or trying to see a bit better with reverse lighting. It's bad when things are so intense you may be causing some glare for other drivers in specific situations, but some OE vehicle lighting is just as bad (Think about stopping behind a vehicle on a very dark road with their left turn signal on and in your face. Some are intense.) The other, and main reason, it's bad to be so bright is it's commonly done poorly. These lights get HOT! Very hot in a short time of being lit or flashing, so this tells me some things. Either the chips are extremely overdriven (which is more common the less there are on the board(s) it seems like) or the heat sink design is very poor. It could even be both. It is also possible to overdrive some chips slightly, although shortening their life, and have heat sinks so good they last awhile. However, overdriving and/or a poor heat sink will certainly reduce their lifespan, which is the concern here for these.Take Sylvania Zevo designs for example. They are not the brightest, certainly, BUT many have a very large heat sink on them that even if the chips were overdriven, it would be very effective. I've seen their Zevo 3157s last FOREVER as DRLs with the high illumination chip on constantly.Heat sink design is a big factor.The pros of this bulb is, for starters, the excellent 360 coverage that seems to fill in a reflector very nicely. Many other bulbs do not do this 100%, leaving some kind of dark spot in reflectors on some vehicle models. They also shine OUTWARDS very well, not just inward to reflectors. This is where a Zevo will lose the battle as they are designed to be inward firing reflector illuminators.The base of these bulbs are precise and secure well into sockets, just like a decent regular bulb has from big name manufacturers. The LED market is flooded with those bulbs that have those cheap bases not made to proper dimensions. You know when you see them. They don't have defined lines, tabs, or shapes and are a bit too small. They look more like "shiny" or "glossy" plastic as well. I've had many fall out in testing. I now avoid those bulbs with those bases that have that look to them.In conclusion? Overall this is a good bulb. There are high concerns they're way overdriven or improperly cooled without a proper heatsink which will cut longevity significantly. Their bases secure well into sockets. Very bright. Very hot.If they kept this design, but reduced the power to the chips (yes they'd be a little dimmer) or improved to a much robust heat sink while keeping the current illumination, I think they'd have a perfect bulb design on their hands.

Just got these light in and installed them and they work perfectly on my 2007 Kawasaki ZZR600! Brake lights are MUCH brighter now!
