Review: Incredible bulbs for the money - VERY impressed on my 2018 Silverado - Update: Got the chance to take two vehicles out for a short memorial day weekend trip and drove behind my wife the whole way to SLC and back, several hours worth of driving each way. These bulbs continue to seriously impress me - I had no issues seeing the brakes or turn signals AT ALL in bright midday sunlight shining right onto the back of the truck (I tried to add a video of this to the review for reference, but it wouldn't upload - still shots from the video are the best I can do for now). They may look a little dim in the pictures, but this is BRIGHT sunlight at high elevation where most brake lights get washed out anyway. The camera is compensating slightly due to the sunlight, and I also have 50% tint on the windshield of the vehicle I was filming from. I encourage you to compare the brightness to the other vehicles in the shots - there isn't much difference between them all. I wish I would have started recording sooner; at the previous intersection there was a new dodge charger right next to the truck, and the Zevo bulbs were just as easy to see as the OEM LED brake lights on the charger! They are awesome for these trucks, hands down the best money I've spent on a bulb upgrade. The third brake light bulb is a VLEDs 921, in case anyone was wondering (insane output, but very expensive at $40/ea). Original review: *The people whining about hyperflashing clearly don't know how LED bulbs work, and didn't bother to read the description and/or look at all of the pictures before buying. Their ignorance is not the fault of the bulbs. You WILL need load resistors to use these bulbs without them hyperflashing or sending "bulb out" warnings* I'm incredibly impressed with these bulbs for the money. I can't overstate that enough...for only having four LED chips per bulb, these are incredible. Will they work in every light housing for everyone? No, probably not - but for a 2018 Silverado, the backward firing LED setup replicates the stock incandescent bulbs darn near perfectly. These Zevo bulbs replaced some JDM ASTAR bulbs with tons of LED chips on them, which were decently bright but had the following issues: 1. The ASTAR bulbs are a side/end firing design. Bright in their own right, but they relied entirely on the bulb itself to produce all of the light output and didn't take advantage of the reflector at all. The end result is that the whole housing filled with a softer red glow, rather than the sharp, crisp reflector cutoff that the stock incan bulbs provided. They may technically be "brighter" than the Zevo bulbs, but a lot of that brightness just gets scattered and wasted. 2. The low to high output of the ASTAR bulbs was very mis-matched. They were too bright when just the tail lights were illuminated at night (making it almost seem as though the brake lights were on), and not nearly bright enough when the brakes were actually applied, especially during the day. The sunlight washed them out horribly, to the point of being almost dangerous when slowing down or signaling/changing lanes The Zevo bulbs, however, solve ALL of these issues. They fire perfectly into the reflector and take full advantage of it. The two smaller LEDs are for the tail light function, and the two larger ones are for the brake lights. This is a big deal, because the bulbs aren't simply supplying more voltage to a small LED to make it brighter. The actual brake LEDs themselves are different, and much more powerful, so when you apply the brakes you are activating a separate circuit inside the bulb. The brake function is MUCH brighter this way, and again, it takes advantage of the reflector perfectly. You get a very nice, low powered glow for the tail lights that isn't obnoxious or confusing to other drivers at night, and a very bright, very easily seen brake light function - even during the day in bright sun. Again, I'm incredibly impressed. Time will tell how long these hold up, but the heat sinks are huge and they seem very well engineered. I'm confident I'll get many years out of these, but I'll update the review with any issues. One thing to note is that you will need to use resistors if you are using these for signal bulbs because they don't draw enough current to avoid hyperflashing. This wasn't a big deal for me because I had already wired them in for my previous LED bulbs, but its something to consider if you're converting to LED from incandescent for the first time. Resistors are cheap and simple to install - lots of YouTube videos on them. You'll have to pardon the quick photos - they may not look that impressive on the camera, but in person there is a HUGE difference.
Review: Brake light compatible! - These LED taillight bulbs are a great upgrade from standard bulbs. The brightness is noticeably stronger, making the taillights much more visible both during the day and at night. They light up instantly and provide a clean, crisp look that improves overall safety on the road. Installation was quick and straightforward, with a perfect fit and no modifications needed. The bulbs feel well-made and have been working reliably without flickering or error messages. I also appreciate how little heat they produce compared to traditional bulbs. After using them for a while, they’ve held up very well and still perform like new. Overall, these LED taillight bulbs offer excellent visibility, durability, and value, and I would definitely recommend them.

## Questions & Answers

**Q: Will this work to replace a bulb with 2 or "dual" filament?**
A: The ZEVO 7443R (red) worked fine in my 2013 Mazda3 to replace the dual-filament (white) halogen bulb. As you'd expect, the one ZEVO LED provides two levels of brightness -- one for regular lights-on taillight use and then much brighter for brake light use. The red color is very intense. While the LED's lumens are about 200% the halogens, they appear to our eyes to be only a little bit brighter. (That's a common perception error. Typically our brains need brightness to improve by about 4x to look like 2x increase.)  I'm pleased with the ZEVOs. And the lifetime warranty is a confidence-inspiring bonus.

**Q: Does this bulb fit 2008 SUZUKI SX4 Crossover brake tail light?**
A: I had a 2006 Suzuki XL7,it dose fit the tail light

**Q: Do these fit 2014 Honda Accord Sport brake light replacement?**
A: Hello Danian, If you're ever curious if this bulb, or any of our SYLVANIA Automotive Lighting bulbs are the right fit for your vehicle, please be sure to check the User Guide below under Technical Specifications, as we update this annually to ensure you know what bulbs work with what model cars. Hope we were able to help!The SYLVANIA Automotive Lighting Team

**Q: When putting these bulbs in a 2015 gmc canyon and tried to use the turn signal right or left  it give error message anybody know why and how to fix?**
A: Change to an electronic flasher, direct replacement. No wiring, don't have to worry about heat from the resistor.

### ⭐⭐⭐⭐⭐ Great replacement
*by A***R on July 18, 2025*

These were a perfect fit on my 2016 Mazda's tail lights. Car came stock with halogen bulbs but these were plug & play and worked perfectly without the need for any modification - no flashing. Nice and bright, great value.
