Why did Lasfit develop T-Series LED turn signal bulbs?
You may have heard that the CANBUS / load resistor is required when replacing the halogen turn signal bulbs with after-market LED bulbs. Installing low-quality LED bulbs for turn signals, you will get hyper flash or error code warnings on the dash. Many users also complained that LED turn signal bulbs are not bright. Thus, Lasfit developed the T-Series LED turn signal bulbs. The T-Series has higher lumen output, a built-in CANBUS resistor, and NO hyper-flash.


Specification
CANBUS ready, plug and play
Lasfit T-series LED bulbs are designed with a CANBUS system in mind. No extra load resistor or additional wiring harness is required. Plug and play for easy installation.

Higher lumen output.
The max wattage on the T-Series bulb is 24W, and the max output lumen is 2400LM. LED bulbs use less energy and are more efficient than halogen ones. Lasfit T-Series LED turn signal bulbs are much brighter than halogen turn signal bulbs.

Intelligent Temperature Control (ITC)
An excellent Intelligent Temperature Control system will protect bulbs against excessive current and overheating and ensure a longer lifespan.

Safety Protection
A built-in mini fuse protects the bulbs and your cars against the instantaneous high current for safer installation and use.

About Lasfit switchback LED turn signal bulbs
YouTube Video Review
Switchback LED turn signal bulbs are designed for dual-filament bulbs only, such as 7443, 3157, 4257, and 1157. Generally, they are used for front turn signal lights. The switchback LED bulbs are white(in low power mode) and amber(in high power mode). When you turn on the DRL or parking light, the white light will be on. The bright amber will be on when you turn on the signal or hazard lights.
Notice:
If the stock halogen bulbs on the vehicle are dual-filament, such as 1157, and work as turn signals only, with no function of daytime running lights/parking lights. Only the amber light will work on the switchback LED bulbs, and the white lights will not work.
