GTR Lighting LED Bulb, H4 / 9003 Ultra 2, Universal Upgrade for Forward Lighting & Fog Lights, Top Quality and Brightest Pure White Plug and Play Replacement, IP68 Waterproof Design (1x GTR.LED738)

 
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.
