Would it be worth changing out the Headlamp bulbs on my-?

I have a 06 Chevy Silverado and was woundering if I should change the headlight bulbs to those new white lights that they sell. I am not sure how much better these work than just the normal bulbs? What brand would you reccomend, I have heard of those silver star bulbs before but don%26#039;t want to replace origional bulbs unless it would be worth it?|||Consumer reports did a test on the mercury vapor bulb compared to the original equipment bulbs and found no difference in site distance or quality of light. I was once thinking the same as you. Save your money
