We can all relate to that annoying moment when we find out a turn signal light bulb has gone bad. It usually happens in a few different ways.Either you notice the obvious abnormal blinker, or you get a new error-code light letting you know it's time to replace your bad turn signal light bulb.The less ideal way to discover your new problem is while driving at night.For many, a bad light bulb is the perfect reason to trade out the stock halogen turn signal light bulbs for improved LED light bulbs. That's because LED is better and brighter. Let's be honest, who doesn't like the sound of that?If your halogen bulbs are still working fine, but you simply want the LED bulb upgrade, there's no harm in admitting that. That makes a lot of sense too! Finding ways to improve different areas of your vehicle is always fun.Regardless of your reasoning, there are many factors pointing to LASFIT being the best option for you.Let's list out the 3 reasons why you should switch to the LASFIT T-Series LED turn signal bulb.The LASFIT T-Series LED turn signal bulb has been carefully researched and developed to ensure it meets the needs of our customers. We spent countless hours continuously improving the manufacturing process due to real customer feedback (we listen to everything you say!).Now, we can proudly say our T-Series LED turn signal bulb provides everything you could ask for and addresses the most common issues.Here's why you should make the switch.Plug & play, easy to installThe LASFIT T-Series LED turn signal bulb ensures a hassle-free installation. We developed it, so it's as simple as installing the OEM halogen bulb. You don't have to worry about cutting or splicing wires. You don't have to worry about adding resistors, or any additional parts.Our LED bulb is polarity protected, which means it won't light up if you installed it incorrectly. If the LASFIT bulb doesn’t light up, then turn it around and reinstall. It should work now. The polarity protection feature lets you know the bulb is installed correctly. Features a built-in resistor function, prevent hyper flash and error codeThis means the LASFIT LED bulb is fully compatible with your vehicle.Normally a LED bulb will trip the onboard vehicle computer system (CANBUS) and cause error lights to pop up on your gauge cluster display (along with constant hyper flashing, or sometimes both). The solution to this issue has been to add an external resistor or relay. This is very troublesome for a few reasons.The external resistor is tricky to install and might require you to pay an expert to get it done properly.The external resistor will regularly reach extremely hot temperatures. That means it has to be installed safely and securely. We have seen cases where the resistor gets loose, due to a poor installation job, and melt through the entire forward light housing unit. Extremely hot aluminum may melt the plastic of housing.Our built-in resistor function works perfectly with the on-board vehicle computer system. We tested our T-Series LED turn signal bulbs on many different vehicles, such as the Honda Accord, Hyundai Elantra, 2004-2018 Ford F150, 2019 Ram 1500, Toyota Sienna, Nissan, Infiniti, and various others.They all worked with no problems. After testing our LED bulb on a wide range of different makes and models, we are confident they will work great on most vehicles. If you find our LASFIT T-Series didn't work for your specific vehicle, report it to us and we'll try our best to fix it, warranty it, or offer you a refund.You can rest assured you won't see any error-code gauge cluster lights, or have to deal with an extremely hot external resistor. But, the LED bulbs will become hot with extended usage (which is not as bad as it sounds, see explanation below).Significantly brighter than the stock halogen bulbThe difference in brightness is very noticeable. Everyone else on the road will clearly see you when you use your turn signal, and that’s precisely what you want. If you're looking for a brighter LED turn signal bulb, then our LASFIT T-Series LED bulb will certainly meet your needs. The LASFIT T-Series turn signal LED bulb comes in two color options: amber yellow, and switchback. Both are amazingly bright and suitable for different style preferences.The pure amber option means both the turn signal and parking light will shine in a bright pure amber color. That’s 3000K.The switchback option means only the turn signal will be in amber, while the parking light/daytime running light will be in a vivid white (6000K). When you turn the signal on, it will switch between white and amber.The decision is ultimately up to you. Both variations look amazing.Check out this video if you want an exact demonstration of the bulb's brightness:There's one other thing we should mention here that comes up very often. It involves the hyper flash function the LASFIT T-Series LED turn signal bulb comes with.Each bulb has a built-in Intelligent Temperature Control System (ITCS). If the bulb is left turned-on for an extended period of time, roughly over 5 minutes depending on the working environment temperature, then it will begin to hyper flash. This is the built-in Intelligent Temperature Control System warning you the LED bulb is getting too hot.All you have to do is turn off it for a few minutes, in order for it to cool down, and it will go back to functioning properly. This is very common, so don't get worried or concerned if it happens to you. If you have any questions about this particular LED bulb, contact us directly, or feel free to leave a comment below.
