-FAQs: Everything You Need to Know About T3 LED Bulbs-

Q1: Whats the difference between T-Series and T3-Series turn signal lights?

Brightness: T3-Series offers optimized brightness to prevent blinding oncoming drivers.
Decoding: New resistor for longer, more efficient decoding.
Lifespan: T3-Series has a heat filter for better heat dissipation and longer life.
There are more details on the differences between the T series and the T3 series.

Q2: What are Switchback 1157 LED Bulbs?

A: If your vehicle uses 1157 dual-filament bulbs, one bulb controls both the turn signal and parking light. Switchback LEDs change your front parking light from dim amber to bright white.

Q3: Whats the difference between 1156, 1157, and BAU15S bulbs?

A: Many customers ask us about the differences between these bulb types. The key differences lie in whether they are single filament bulb and the angle of their two contact points. Lasfit’s T3 series covers all these models. You can check out Lasfit’s blog to get more detailed information about the different between 1156, 1157, and BAU15S bulbs.
