2023 Upgraded LED Turn Signal Light-T3 Series BAU15S

Lasfit T series LED bulbs are specially made for turn signal lights, high brightness, and a built-in canbus decoder, no extra harness or load resistors are needed, plug and play, it's very convenient to replace the stock halogen turn signal light bulbs. Lots of people have got Lasfit T series LED bulbs and most of them are satisfied with their performance. T series LED bulbs are not perfectly compatible with some vehicles or can't work stably on some specific models and caused error code or hyper flash. Lasfit always deeply cares about user experience and has upgraded the T series based on customers' feedback.

What are T3 Series LED Turn Signal Lights?

Upgraded Can-Bus Decoder System

The most annoying thing for users is that compatibility problems such as dashboard errors, hyper flash, or working stably for a couple of minutes then starting hyper flash, frequently occur after replacing LED turn signals with LED bulbs. The built-in canbus decoder of T3 series LED bulbs increases the wattage to match the OEM computer inspection system and prolongs the decoding time, no error code, and you don't worry about hyper flash after working for a few minutes.


Softer Output Amber Lighting

Some customers complained T series LED turn signal bulbs are a little bit too bright and glare at other traffic, so the T3 series is reduced luminance. Equipped with 20 high-light flip chips, the bulbs provide 2000LM and 24W of lighting, ensuring sufficient brightness for your vehicle. Additionally, the soft beam pattern helps prevent flashing to the side of passers-by.

Built-in Intelligent Temperature-Control System

Excellent Intelligent Temperature Control system will protect bulbs against excessive current and overheating and ensure a longer lifespan.


Safety Protection

While other LED bulbs on the market have sacrificed heat dissipation due to their small size, Lasfit has listened to user feedback regarding bulb lifespan and focused on developing T-series. These LED bulbs utilize smart IC chips and fuses, as well as aviation-grade aluminum for superior heat dissipation. Additionally, a built-in thermal insulation layer further enhances heat dissipation performance to provide a longer lifespan for the bulb.

Replaced the incandescent bulbs on my 2022 Honda Accord with these LED bulbs because they were the only old style bulbs on this model and looked dated and out of place amongst all the other LED around them. Loving the result. They are tons brighter, almost too bright, but outdoors/in the sunshine I’m ok making sure people behind me are keenly aware I’m changing direction. Hoping they last, only time will tell, but I appreciate having this option available. Replacement was very easy, you just need patience and finesse removing and replacing trim pieces so as not to break the taillight and related parts.
Photos show comparison with one bulb done, and both bulbs done. IRL blinking is much quicker to full brightness and faster on and off, as expected.

I had a hyperflash issue with the previous version of this turn signal bulb. I contacted Lasfit and they sent this upgraded version to help address my issue. Very simple and quick replacement. These turn signal bulbs aren’t as bright as the previous version, which is a good thing. The previous version was too bright, especially at night. Lasfit customer service is very quick to respond to customer inquiries and provide favorable solutions.

I purchased the PY21W LED Turn signal bulbs for my vehicle and had them for over a year. I enjoy how bright the bulbs are and it is a huge improvement from the stock halogens my vehicle came with. I noticed that if you leave the turn signals on while waiting at a stop light for about 5 minutes to make a protected turn, the bulbs will shut off and start to hyperflash. The only way to fix is this by turning the vehicle off and turning it back on. This is not right where I have to pull off the road to restart my vehicle so my turn signals can operate again. I know it is to control the temperature of the bulb and ensure longevity but I believe incandescent bulbs get much hotter than these bulbs and still last longer without having any operational issues. Apparently, there is no fix for this or an updated version for the T Series bulbs.

As we mentioned on the product page, since these bulbs built-in Intelligent Temperature Control, if you use for a long time (a few vehicles maybe 2-5 minutes, it depends on year/make/model and temperature) may happen hyper flash, please turn off and cool 1-2 minutes, they will work properly again.
