I've used the Silverstar's as well -- but in my experience, there isn't a ton of difference between any of the DOT legal 55W bulbs. If you're serious about more light -- up the wattage. If you do that, be sure to re-aim the lights, properly aimed so you're not blinding oncoming traffic. And unless you want to melt the stock lighting/wiring components -- go to www.danielsternlighting.com and install separate relays/big wires for your lights. Increasing the V at the light bulb makes a HUGE difference in lumen output, even with stock bulbs. I run the Euro Hellas with 80w/100w bulbs and separate (4) relays for low beam and high beam on each side. 0.00V drop between alternator and the bulb - getting a full 14.5V at the light. BIG difference in light output with any bulb you choose.
