Oh, sorry, I hadn't realised you were asking for advice on headlights too.

Have you only got the stock lenses in place?

Decision 1: Stay halogen or go HID?

HIDs will scatter light awfully and dazzle oncoming cars if installed in stock lenses.

They're better installed in Raybrigs or Rogue units.

Either way, they may well make you fail your MOT.

Decision 2: Colour temperature?

As I said above, the temperature of your

"white" is what you'll be looking to match.

The bluer you get, the less light you're putting out onto the road

- 3000k-3500k tends to give the best illumination.

Halogens range from about a yellowish 2000k to a nearly daylight neutral 3000k for the premium units.

Anything bluer than that tends to involve tinting the bulb's glass and thus reducing the light output.

HIDs Can start as low as 3000k, but, as I said about, 4300k is more common, which is as near as makes little difference daylight neutral.

High colours

(6000k and above) reduce light output and again start to look rather blue.

Decision 3: Finding 501s to match.

Standard 501s will match standard Halogens.

Once you get a premium halogen, a standard 501 will look rather yellow, but there are xenon matching 501s around, which should also match 4300k HIDs relatively well.

Once you're up at 6000k, you really want an LED 501 to even attempt matching the colour.

My advise would be to avoid a HID install or cheap

(read c**p) blue tinted bulbs like you posted there and get some quality halogen bulbs, together with some 501s designed to match factory fit HIDs.

Having driven with standard halogen in stock lenses, 6000k HIDs in Raybrigs and Osram Nightbreakers in Rogue quads

(each with matching sidelights as detailed above) I can easily and honestly say the best to drive with are the Osram Nightbreakers with the Philips Blue Vision 501s.

That's what I would recommend to fit to any of the headlight options available, particularly if you're running the standard lenses.
