Stay with OEM! They do fine and will last much longer and won't cost you an arm and a leg.
Updating my comment and rating. After riding at night, these are terrible. They are not very bright at night. Will be replacing with Autozone H7/55W Sylvania SilverStar bulbs. These Kuryakyn bulbs are over priced. Any retailer will sell a pair for less than Kuryakyn's cost. I assure you that you are better off buying the brand I just bought, unless you don't mind a dim bulb at night.
I am not 100% sure how bright these really are. I have driven at night and can still see the road ahead of me. The benefit to these are the color of the light. Rather than a yellow color from the stock bulbs, these are white. I haven't replaced the high beams yet, but will need to do soon since the two don't match.
Otherwise, the company offers a lifetime guarantee on the bulb.
I bought 4 of these thinking that they would help... They seem a little brighter than stock however not enough for me to keep them on the bike. I traded them out for the most popular Ultra Bright brand and the local Autozone and feel that the results are much better.
And we can't wait to show you how it's done!
