Very bright and no hyper flashing w/ capacitors.
I was very skeptical with buying this product especially when a lot of reviews stated these hyper flash. Well, I took a chance and ordered these and let me tell you. I am VERY happy with the quality and results. The bulbs themselves appear to be great quality and the instructions were straightforward. Once installed the bulbs work just as promised and the capacitors do their job, no hyper flashing. Buy with confidence and you won't regret it!

very bright and easy to install!
these things are super bright and increase visibility a lot! they include resistors to stop hyper flash and they don't care which way they are plugged in! love the cool look and easy install. will always use these when needed- currently on my 1998 Mazda B4000 and my 2010 raptor f150- both look great!

Excellent product quality built
I missed it but it does come with resistor easy install once you figure out your wiring what is blinker and running light. Love the look and helps the led headlight a a good bit. Blinker are much brighter. I would buy again!!

Does not Fit "Front" Signal Lights for a 2006 Nissan Frontier.
Does not fit Nissan Frontier 2006 "For front signal lights only" As far as rear signal lights, brake lights, and Reverse lights, they will fit fit. Just don't buy them for Front signal lights as they are to long and you won't be able to lock them in place without damaging the glass dome. Took off Two Stars for that reason and a bit pricey for cheap prong connectors and not being a more solid board connector as well as Claiming they fit for signal lights on a 2006 Nissan frontier when it infact does not. For rear Hazard lights, I got the clear ones and got no hyper flashing. Once I attempted to use the Dual White/Amber Versions for front lights, which did not fit. I got hyper flashing, they do come with two big solid resistors, but I didn't use them, because they didn't fit for front signal lights. As for rear lights works they worked perfectly without hyper flashing. Fixture seems well made, but instead of it being a board for prong connection, it has cheap progs that seems to cause overheating issue of most LED lights. Not sure if it would be the case, but for most, those prongs over heat. Product is very well made, Aluminum Housing. Nice solid Thick glass dome light at tip for even lighting. Will be contacting support and see if they can provide me with a extension for front signal connector so the length can fit. Otherwise I will have to return them 🤷🏻♂️

BEST LED SWITCHBACKS
If you have one of these older GM trucks, I recommend AUXITO led bulbs over anything else on the market. You will need to add resistors to each turn signal because the old system on these trucks will make the led hyper flash but that’s normal and common and a 10 minute fix with a youtube tutorial and about 8 bucks worth of load resistors. Had these for a couple months now with zero issues and i love them, no flickering no burning out absolutely no problems and nothing negative that could be said. Gives a beautiful nice modern white and then switches to a bright amber when using turn signal or hazards. If you throw on some clear headlight housings it’ll really make the lighting pop. My picture shows how they look with brand new headlight housings and the video shows the turn signal being switched from white to amber with the stock headlight housings. Thank you auxito for creating the best bulbs on the market

10 Stars ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️
I tried a couple of others – they were not very bright or appeared to be very poor quality or Both. these are well worth the money. One look at them and you know you are dealing with a quality product with a projector end And close to the length of the original bulb so they do not look strangeI Especially like the two color switch back – so the parking lights look like driving lights (white) with the beautiful bright amber turn signal - the high side turn signal does not go Amber - White - Amber like some - these have fewer larger LEDs – which looks a lot better than some - also I learned my lesson to buy the resistors with the built-in harness/plug - Much easier to install and more reliable - 2007 GMC Yukon

Orange/flashing lights won’t work!
first bulb was fine! everything worked how it was supposed too! white when not flashing, orange when the blinker is active. however second bulb did not flash. stayed white when blinker was off, on activation the whole light just goes out. no flash, no color, no nothing. and no it is not the vehicle. i have tested the bulb socket with multiple other bulbs including the other one that this one came with. all work fine. i am very disappointed.

08 silverado switchback signal lights
Items thru mail nicely packaged and on time. Although it says in the description that it comes with resistors I didn't read that far into it and was surprised when I seen them because I obviously needed them for install without them I was getting a hyper flash. They also send you quick connect clips to tie them up which is a plus. They look great for what I was looking for gives me more light up front since I got leds for headlights and it gives my truck a modern look with the switchback to amber when signal is going which are a nice bright amber. Definitely recommend

I recently purchased the LED turn signal lights with running light from Amazon, and I have to say I'm thoroughly impressed. These lights are well-made and offer excellent visibility on the road, which is crucial for safe driving. The installation process was straightforward, and the instructions were easy to follow. The lights fit perfectly in place of my old ones, and the wiring was simple to connect. I appreciate that they came with all the necessary hardware, so I didn't have to purchase anything else separately. The turn signal lights are bright and clearly visible, even during daylight hours, which gives me added confidence on the road. The running lights are an excellent addition as well, providing a subtle yet noticeable glow that adds to the overall look of my vehicle. I also appreciate that these lights are energy-efficient and built to last. LED lights typically last longer than traditional incandescent bulbs, so I expect these to be a long-lasting and cost-effective upgrade. Overall, I highly recommend these LED turn signal lights with running light to anyone looking for a safe, stylish, and durable lighting solution for their vehicle. They're a great value for the price and offer excellent performance.

Easy install. Load resistors are included in box and are needed to prevent hyper flash. The amber looks great, as does the bright white parking light. For those wanting to run amber as running lights, know that wranglers light up the blinker not the parking light so your resistors will be energized whenever you are driving. Which mean they get really hot and should be mounted somewhere that won’t melt. Good quality light. Shall see if it stands the test of time.

Very bright and look great. Only issues I’m having so far is the one resistor is hit and miss. Sometimes it hyper flashes and then randomly corrects it’s self. Will be contacting to get a replacement resistor then will update my review. ***Edit*** Spoke with the company and they sent me new resistors to correct the problem. 5 star review now as they stood behind their product.

Had these bulbs for 5 months now, they are still going strong. The white is bright and adds a nice clean modern look to my car and they switch to amber when you signal/Hazard and they are very nice and bright. One thing to note is that the resistors to stop hyperflash are not attached to the lightbulb itself, but rather you have to splice it into the turn signal cable. This could lead to the wire getting exposed and becoming damaged so I have just been running them with hyperflash because I dont want to cut the wire.
