18 months ago I changed the dipped beam bulbs to Phillips X-tremeVision.
I found the original dipped beam quite poor although the full beams were fine. They all use the same H7 bulbs so it must be more of the design of the reflector then the bulbs themselves.
However, I decided to give the Phillips a go, the light pattern has been much improved and is brighter without any problems of affecting other road users. I had concerns over reports of them not lasting long but mine are doing just fine so far. They were easy to change from under the bonnet without needing to remove any panels or obstructions, it is important not to handle the glass parts and I expect this might account for other users to experience failures.
Certainly an easy and worthwhile upgrade.
