## Description

Product description Do You Know Why Choose OXILAM 7440 LED Turn Signal Light Bulbs? - When you want to upgrade turn signal lights, amber yellow is the suitable color for turn signal lights which is better than the white light bulb to get people's attention on the road. -Unlike most of other picks on the market, these 7440 bulbs deliver a full 360-degree illumination with a projector-style lens and 26 PCS 3020 SMD LED chips which is 500% times brighter than stock lamps. -Uses an aluminum heat sink to regulate heat and disperse it into the atmosphere, preventing it from overheating. It also comes with a heat resistant LED base for support that provide 60,000+ long lifespan. If you are not sure if these bulbs are suitable for your vehicle, you could do the following Use desertcart filter system to check. (But it may not be 100% accurate or up to date) Check your owner's manual or stock bulbs . (The part number is marked on the bulb.) Search online for " automotive bulb look-up " in order to identify the bulb you need for your vehicle For vehicles with fitment sensitivity (e.g. 2006 Honda Civic EX) , or if you’re still unsure, we recommend leaving your vehicle info (year/make/model) in the Customer Q&A section — assistance will be provided as needed. Here are some warm tips for you before your purchase For certain vehicle models such as Jeep, Chrysler, Chevrolet, GMC, Dodge, RAM, and Volkswagen, the built-in load resistor may not fully eliminate hyper-flashing due to system sensitivity. In such cases, installing additional external resistors may be necessary to ensure proper function. The desertcart filter may not always be accurate . Even if the filter indicates a match , it’s still recommended to confirm the correct bulb type based on your stock bulb part number or vehicle’s owner’s manual . 7440 bulbs are single-function , made for turn signals only. They do not support additional functions such as parking or daytime running lights. If your vehicle requires dual-function lighting, please consider a 7443 LED bulb instead . Should you encounter any issues with the purchased product or require further assistance, please don't hesitate to reach out to us via desertcart email . We are committed to providing timely solutions or alternatives to address any concerns you may have. This bulb is intended to replace standard models including 7440, T20, 7440NA, 7441, W21W, WY21W, and 992. To avoid misfit, please double-check your owner’s manual or original bulb base to ensure compatibility before purchasing.

Review: "Error-free" Bulbs Come With External Resistors for Some Reason. - 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.
Review: Replacement Received in only 4 Days after my Review, Great Customer Support. - Purchased 2 sets of these for my 2025 RAV4 they are very bright however, after just 2 months one bulb failed, car started hyper-flashing but the bulb would not lit during the hyper-flashing which could be dangerous during heavy traffic in the freeway so I had to revert back to the factory bulb. I will contact seller or maker to see if I can get a free replacement bulb. UPDATE!!! Happy to report that the company responded quickly they sent me replacemnet bulbs right away and received them yesterday.

## 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.
