Silverstars will outperform ANY aftermarket bulb out there. Your friend is running 80w bulbs...well it might be fine NOW, but it won't be long before the wiring starts to melt. Silverstars are rated at the factory recommended wattage, so they won't damage anything, and the light output is pretty good. The APC bulbs (or any other aftermarket bulb) has a dark blue coating on the glass...so to see ANYTHING, you pretty much have to buy high wattage bulbs. Just get the silverstars, you won't be disappointed.
