At The Retrofit Source, we do 2016-2023 Toyota Tacoma LED lighting upgrades better!

Craftsmanship: Designing a high-quality bulb is a task GTR Lighting took seriously. Unlike so many companies that skimped on every single detail they possibly could, the GTR Ultra Series 3 features a design that covers every base with real attention to detail.

The Best: While so many others use Philips or CREE LED chips, GTR went with a custom TST 7045 chipset option to ensure better results. Those results show through to the finished product too thanks to digitally optimized LED positioning that most closely matches the original filament tolerances. Combining these features is the key to getting all the light from the source to the reflector surface and ultimately onto your target without wasted lumens and glare all over.

Better Fitment: We've heard many who assume that because the Ultra Series 3 is smaller than competitors that it's weaker and less capable. They couldn't be more wrong. Thanks to TST (Thermal Separation Technology), it is more able to effectively dissipate heat, allowing the emitters to retain high luminous flux output. That results in 4,700 lumens of output and a considerably easier time installing them. There are zero downsides here.

Best Warranty: We can't overstate this. You won't need another headlight bulb after these ones. They're so solid and strong that GTR backs them for life.
