NOW WITH A LIFETIME WARRANTY! This is the last set of bulbs you will ever need to buy! When going for the "Clear Look" with a clear lens kit, Solaris™ InvisiBulbs - UltraBright Edition are a must! Our new ULTRABRIGHT edition is by far the brightest concealed bulb on the market today. It is 2 times brighter than our original SOLARIS InvisiBulbs, and are 3 times brighter than the competition! Solaris™ Electrum™ InvisiBulbs light up amber (like factory bulbs) while turning silver and blending in with the lens when off to remove the unpleasant orange reflection in the lens when off. (Solaris bulbs that illuminate a xenon white color are also available as Niveus™ bulbs). The result is perfectly colorless clear lenses! Our bulbs are made to last hundreds of hours without discoloring or burring out. We guarantee every bulb is delivered to you in perfect working order and will stay that way as long as you own your car! Solaris™ Electrum™ InvisiBulbs illuminate in amber. Solaris™ Niveus™ InvisiBulbs illuminate in a xenon/hyper-white color. Both colors of bulbs are hidden when off.
