03-09 Toyota 4Runner Ultra 3 LED Bulbs (Low Beam)

2003 - 2005, and 2006 - 2009 LED low beam bulbs for the Toyota 4Runner: In 2003, 2004, and 2005, the Toyota 4Runner used an older style halogen reflector headlight and a newer style projector halogen headlight in 2006, 2007, 2008 and 2009. Please select which year 4Runner you have from the options above to make sure you get the right bulb type for your year and headlight style. Both types of headlights found in the fourth generation 4Runner use different bulbs, one will not fit the other, but they both work very well in their correct applications.

We found that LED bulbs from GTR Lighting and Xenon Depot performed the best, and fit the vehicle without modification so those are the two options we recommend for guaranteed fitment and performance.

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.
