Hey dude I'm assuming you're running quads.
FYI: silverstar ultra's are a sham. The regular silverstars aren't too bad because they aren't heavily tinted to filter out yellow light. Phillips Xtreme Vision are one of the best bulbs on the market.
If you really wanna supercharge those quads you can do an H9 swap for the H11 in the low beam. This will yield about 2100 lumens from 1250, so almost double the light output. Because the low beam has a glarecap this shouldn't cause glare to other road users. I haven't actually tried this swap myself but theoretically it'll work. The stock circuit is rated for 15amps so even with the extra 10W you're no where near the limit.
For the highbeam you can run 9011's in place of the 9005's so that'll bring you from 1700 to 2300 lumens.
For the H9's just get regular phillips bulbs. They don't make any special lines for H9, but the upgrade on it's own will be whiter and way brighter. Life is shorter on the h9 compared to the H11 but that's about the only downside. But since you're just buying regular H9's they're cheap
For 9011's just get phillips(Or wagner...) as well.
You will need to trim the tabs a bit with nail clippers but this will take you about 5 mins.
Just google H11 to H9 swap.
For the 9005 to 9011
Should be pretty obvious when you take your 9005 out of the highbeam and hold it up to the 9011 what needs doing same with the h9 vs the h11.
You'll notice this upgrade big time lol
