  • Better than Ever: After nearly a decade of experience developing and refining our designs, sourcing the best quality raw materials, and gathering feedback from end-users on what makes the best LED bulb with the most effective beam pattern; We're proud of the new Ultra 2.
  • This an LED bulb upgrade that is brighter.
  • That has a better beam pattern.
  • Lasts longer.
  • Has more adjustability.
  • And is easier to install.
  • It sets an all-new standard for what products in their class bulbs should be, and we're proud to call it our own.
  • Brighter: The Ultra Series 2 bulbs from GTR Lighting utilize the best automotive grade multi-core LED chip technology to deliver ultra-bright light, in an ultra-focused beam pattern! Not only do the elec-tec automotive-grade NLW753 chips have more lumen density than popular (but now aging) options from CREE and Philips, but there's more to it.
  • We have optimized the position of the LEDs so that once locked into the fog light, they are directly in-line with what the optics of the projector or reflector was designed for which will provide you, the driver the most useful and safe beam pattern.
  • The collars have full rotational adjustability.
  • Put simply: You'll see a lot more, but without producing extra glare to oncoming traffic.
  • More Reliable: Performance aside, these are the last LED fog light bulbs you'll ever need! After many simulations, we arrived at a heat-sink design that is not only extremely effective at keeping the body of the bulb >80C, but looks cool too.
  • Since maintaining low operating temperatures is key to LED lifespan, we've paired that with a bearing-less fan to actively cool the heat sink as well.
  • The housing on our LED drivers is completely potted inside too, which is only possible with expensive-to-produce die-cast housings like the one that the Ultra 2 uses.
  • Keeping cool and all components dry is crucial, and the Ultra 2 checks all the boxes.
  • Better Fitment: We challenge you to find an alternative that produces the same amount of output with the same small footprint that the Ultra 2 has.
  • Here we took a balanced approach between maximizing output and minimizing geometry so that they'll fit in every application.
  • Too much power and an inadequate heatsink? Premature failure.
  • Too much power and a massive heat sink? Great, but won't fit anywhere.
  • Due to their superior optical focus they can create up to 10x more usable light than other LED bulb options even though they only produce 3,900 Lumen of light.
  • If you're looking for the brightest option that's a sure fit, you've found it.
  • Best Warranty: You can hit the road knowing that you'll be backed with a lifetime warranty from here on out.
  • If in the rare case something goes wrong, GTR Lighting will replace the product quickly.
