Otherwise, stick with your stock bulbs.
Most aftermarket xenon gas-filled bulbs are mostly about looks (color) which offer very minimal or no visual improvements over stock halogen bulbs.
my bulbs are colored because they are "all weather bulbs" ideal for low visibility, and inclimate weather.. the "yellow" tint is PROVEN to increase visibility in harsh weather conditions..
