Upgraded 7440 7443 LED Bulb Red for Tail Lights Brake Lights, T20 W21W 7441 7444 LED Replacement for Stop Tail Brake Signal Lights, Pack of 2

When choosing the correct part number, there are a few options to consider. If you have a stock halogen bulb, you can refer to methods 1, 2, and 3 to find the right part number. However, if you have an aftermarket light, the bulb fitment guide may not be accurate, so you can use method 3 to determine the correct part number. The "Note/!" section is crucial, as it will specify the applicable positions for the LED bulbs, such as brake/signal/tail lights. If the bulbs cause hyperflashing or a dashboard error warning, load resistors may be required to resolve the issue, which you can purchase on Amazon or inquire about with the seller.

If Amazon states the bulbs are compatible, but they actually do not fit, you can leave a question on the product page or reach out to the seller through Amazon for assistance in finding the correct part. To check if the bulbs will fit your vehicle, you can use the "amazonconfirmfit" feature on the product page, which will indicate the applicable locations. If one of the bulbs is defective, you can contact the seller through Amazon to request a replacement.

These LED bulbs are non-polarity and can be used for various applications, such as brake lights, tail lights, stop lights, parking lights, daytime running lights, etc. However, some sensitive vehicles may encounter CAN-bus issues after installation, in which case load resistors or a flasher relay may be required. You can reach out to the seller through Amazon Buyer Message to get help and solutions for these issues.

One of the key features of these LED bulbs is their low power consumption and high brightness. At 5.5W per 7443 LED red bulb, they consume only 1/4 of the energy of the original 7443 red bulb but provide 4 times the brightness. The built-in smart IC driver ensures constant current and no radio interference, with instant-on capability and zero warm-up time.

The unique design of these LED bulbs resembles the shape of halogen bulbs, with 54 precisely arranged 4014-SMD LED chips delivering 360° high luminous efficiency and a full amber light output, making them easier to notice and safer for driving. The small size of these bulbs is comparable to OEM 7440 bulbs, and they are non-polarity, compatible with US standard and CK sockets, fitting a variety of part numbers such as 992, 7440, 7441, 7443, 7442, 7444, W21W, WY21W, 7440NA, 7440NAK, 7444NA, 7444NAK, and 7443LL.

The electroplating process used in the housing improves oxidation resistance and produces less heat, while the high-end styling ensures a great match in the assembly. These LED bulbs make an ideal replacement for your halogen 7440 red bulbs, offering superior performance and a sleek, modern appearance.
