I fitted the Philips Bluevision bulbs into my lights, they give a definate Upgrade I bought them from
www.powerbulbs.com you wont be dissapointed
Now when I drive other cars I notice the difference and see how really good the lights are on my car.
Two other things to check are the beams are in correct alignment and if you have electrical adjusting lights that the adjuster is in the correct position so they are on their highest setting.
