Xtreme White Plus is PIAA's best-selling technology. These bulbs will provide a brilliant Xtreme cool white light that will light up road hazards and street signs long before a normal halogen bulb. Xtreme White Plus bulbs are engineered for sustained Performance in applications where a high level of vibration and moisture protection is required. PIAA bulbs are engineered with XTRA Technology for greater Performance per watt compared to the competition. XTRA Technology is achieved when a proprietary gas mixture is combined with an aerospace alloy filament that produces greater light output than its rated power consumption: i.e. 55W=110W
I installed 4 of these H7 bulbs into my 2014 Goldwing. I can't really tell if they are actually brighter, but my friends that ride in front of me say they are. I wanted brighter bulbs without the additional amperage draw on the system. The reason is that the headlights run through the start switch. More powerful, higher amp bulbs will cause the switch to overheat and then the bike will not start. Typical on Honda motorcycles.
<p>Brighter than other competitive brand. A little bit pricey but of course you pay for the performance and the quality.</p>
