Ultra Series Bulbs
The Ultra Series LED Bulbs from GTR Lighting feature ultra-bright and ultra-precise Philips-Lumileds Luxeon Z ES LED chips. They come in 2 styles: super bright LED headlight/fog light bulbs, or a less bright fog/DRL version for accent lighting. If you need a bulb to make your headlights or fog lights brighter, take a look at the 3,700 Lumen LED Headlight bulbs below. If you just want cool looking DRL/Fog lights, or bright reverse lights, take a look at the cheaper, less bright Ultra Series bulbs.
