Ramone,

I have similar bulbs in my Jeep with IPF lenses, and am considering them for the Cobra. They REALLY do help light up the road well, don't they? Well worth the extra cost to be able to see so much better at night, IMHO.
Here's a site that demos the difference compared to 'normal' bulbs and lenses.
