Review: Super Easy & Quick Install - No Issues :) - These bulbs have been fantastic, super bright and clear with no hyper flash or any warning messages on my dash. Will note if your vehicle uses the turn signals as parking lights the bulbs will shut off (unless given full power i.e - if you use your signal) overall great product, would highly recommend you’re looking for modern sleek look :) Also please note if you have the turn signal on for quite some time the bulb will dim to prevent overheating, this is normal and is done to prolong the life of the unit.
Review: Anti Hyper, no canbus error. These bulbs have protection for overheating. - Great product, installed on Infiniti QX70 as turn signal bulbs for front and rear. No canbus error, excellent brightness and crisp amber color. Slightly harder to install since the bulb is longer but it did fit. I hope they last long since these bulbs have overheating protection.

## Features

- 【Smart CANBUS design】 Built-in error-resistant decoder allows direct replacement of original bulbs, preventing dashboard fault codes. Plug-and-play operation eliminates the need for additional resistors or decoders, simplifying the installation process.
- 【Superior LED technology】 Utilizing high-performance LED chips, it produces a brighter, more eye-catching amber glow than traditional halogen bulbs, greatly improving the visibility of turn signals and enhancing driving safety both day and night.
- 【Anti-Hyperflashing】 A unique circuit design effectively prevents turn signals from flashing at excessively high frequencies, ensuring signal frequencies comply with regulatory requirements while maintaining the stable flashing rhythm consistent with the original vehicle.Note:This product flashes at a very high frequency on Dodge Ram trucks. If you own one of these trucks, please exercise caution when purchasing.
- 【Durable and Energy-Efficient】 LED technology consumes less power, reducing strain on the battery. Its filament-free structure resists shocks and impacts, with a theoretical lifespan of tens of thousands of hours—far exceeding halogen bulbs—minimizing the hassle and cost of frequent replacements.
- 【Buy with Confidence】 If you have any questions about the product, please contact our team promptly, and we will provide you with the best solution.

### ⭐⭐⭐⭐⭐ Anti Hyper, no canbus error. These bulbs have protection for overheating.

Great product, installed on Infiniti QX70 as turn signal bulbs for front and rear. No canbus error, excellent brightness and crisp amber color. Slightly harder to install since the bulb is longer but it did fit. I hope they last long since these bulbs have overheating protection.

### ⭐⭐⭐⭐ Check if you have clearance
*by K***I on September 29, 2020*

I bought these for myself, but my turn signal housing was barely enough to fit. It was touching the plastic and these do get hot in a short period of time. I ended up giving it to my brother and it fits just nicely in his car. I just happen to be unlucky, but they do function pretty nicely and are very bright! Have not hyperflashed on him since!
