## Features

- 600%+ Brightness: (Pack of 2) These 7440 led bulbs come with 26 pcs 3020 SMD LED chipsets, 4000LM, 2200K amber yellow, Voltage: DC 12-24V, Power: 21W/PC, 6 times brighter than the halogen and energy saving.
- No CANBUS Error Guarantee: Compatible with both CK/SRCK and standard sockets, fitting 95% of vehicle computer systems seamlessly. However, for specific sensitive models like JEEP, CHRYSLER, CHEVROLET, GMC, DODGE, RAM, and VOLKSWAGEN, or when using multiple pairs, flickering or error warnings may occur. To improve performance, the built-in CANBUS driver has been fine-tuned to reduce error codes and hyper-flashing. For vehicles requiring additional support, external load resistors can be arranged where necessary to help restore stable function. If such a problem occurs, LET ME KNOW, and we will provide free load resistors。
- Double Heat Dissipation: Aircraft grade aluminum body built and unique bump appearance design increase the heat dissipation area. Wide voltage & constant current provide up to 60, 000 hours lifespan.
- Fit socket: These LED bulbs are just replaced for 7440, T20, 7440NA, 7441, W21W, WY21W, 992 Bulbs. Please use the "VEHICLE FITMENT GUIDANCE" or CHECK YOUR VEHICLES OWNER’S MANUAL before purchasing to ensure compatibility with your vehicle. Due to possible socket variations across trims or model years, we recommend checking the original halogen bulb part number or using the desertcart mail to confirm compatibility with your specific vehicle.
- Important Note: These 7440 LED bulbs are designed for turn signal use ONLY. They are single-function bulbs and not suitable for DRL or parking light applications.

## Questions & Answers

**Q: Are these slightly brighter than stock or abnoxiously brighter ?**
A: Moderately brighter.  Not horribly bright but 50% brighter than stock.

**Q: Is the 2800 lumen rating per bulb or pair?**
A: Hello, for pair.

**Q: I have a 22 tacoma, and i added these to the brake/turn signal rear, and i get hyper flash only when the lights are on. different bulb in brake**
A: Dear,
For some newer models, such problems may occur. Can you contact us via Amazon email to obtain the load resistor?

**Q: i have 2013 odyssey will this hyper flashes? and what else do i need?**
A: My 2007 4Runner now hyper-flashes, it's very disappointing because it's the only reason I went with these. I don't think the 99% thing is accurate.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect Fit for 2009 Mercedes CLK 350 — No CANBUS Issues!
*by G***Z on May 28, 2025*

I bought this LED bulb set for my 2009 Mercedes-Benz CLK 350 rear turn signals, and I'm happy to report that they work perfectly without triggering any CANBUS errors. If you own a Mercedes, you know how picky these cars can be with aftermarket bulbs, but this product did not disappoint.Installation was straightforward, and the bulbs are bright, crisp, and a significant upgrade over the factory halogens. They give a clean amber light that looks modern. I’ve had them installed for a few weeks now with no flickering, no dashboard warnings, and no issues with fit.Highly recommend if you're looking for a plug-and-play LED upgrade that won’t trip the CANBUS system on older European models like mine.

### ⭐⭐⭐⭐⭐ 1/2 price of Lasfits and just as good I think. Added this brand to my goto LED manufacturer list
*by I***I on September 8, 2025*

Amazing. Saw youtber recommend them and reviews good even though I usually stick to Sealight, Fahren, Alla Lighting and Auxitos (Auxitos often faked but real ones pretty good and cheaper) having bad luck with cheap no-name brands. But Oxilams I think are good. They make a load resistor turn signal and they're 1/2 the price of Lasfits. These are bright, do not Hyper flash and make a huge difference. I feel safer driving when I signal, honestly.

### ⭐⭐⭐⭐⭐ "Error-free" Bulbs Come With External Resistors for Some Reason.
*by J***H on May 28, 2020*

Edit: I got a chance to install the bulbs in my wife's car and they work as advertised. I can't tell if it's because the load circuit built into the bulb just happens to be sufficient for her car and the included load resistors would still be necessary for other vehicles, but they definitely do include a load circuit and driver in the bulb. (It was raining and I didn't have the ability to put them thru exhaustive tests with meters, plus I don't know what resistance the car looks for.)The bulbs are super bright and have a color temperature that's easier for the human eye to see than the OEM amber halogen bulbs. No one's going to miss it when my wife changes lanes or makes a turn. The instant on/off of the LED vs the fade in/out of the halogens is very eye-catching and, along with the added brightness, should increase visibility especially on bright days.I suspect that there's a holdover in the packaging method that put the unneeded resistors into the packaging. They may have originally shipped with non-CANBUS bulbs and were just packed in by mistake. (I guess I've got two extra load resistors and heat sinks hanging around for future projects now, because these aren't going back.)Review adjusted to 5 stars. While there was some initial confusion that could have been easily avoided, the product works as expected and advertised. Well worth the price and easy to install in the car I'm working with (2013 Hyundai Genesis Coupe).See Edit. For now I'm giving these a 2 star review based on the difference between the ad and the package. These arrived today and, full disclosure, I haven't installed them yet. The ad lists that there's a built in load circuit, but yet these still come with load resistors in the box and instructions for how to install them.That the resistors are included rather than sold separately is nice, however, the point of CANBUS bulbs is to not produce errors and avoid cutting into the wiring with load resistors (as well as avoiding the minor hassle of positioning the resistors to dissipate heat). These were advertised to not need resistors at all. At this point I can only assume that either the bulbs don't have built in load circuits as advertised, they're potentially underpowered and will only avoid errors and hyperflashing on some cars, necessitating the use of additional resistors to compensate, or I somehow got the wrong item. Nowhere in the ad is it mentioned that anything other than the bulbs themselves are included, so seeing load resistors in the box was an unpleasant surprise.I'll be installing one bulb tomorrow to see if it produces an error or hyperflashing. I'll update my review accordingly. If the resistors are required to make these truly error free, I'll be returning them as they're for my wife's car and I'm not willing to cut into her wiring when I know there are bulbs that don't require it (I have several in my own vehicle and two in her front signals, but I didn't want to use switchbacks that might blind drivers behind her or appear to be reverse lights while they're not flashing).Hopefully this is an oversight, or mistake, but I wanted to give fair warning to anyone who considers purchasing these before I can determine the reality of the situation. I'll update when I have more information.
