Can anyone see a problem or has experienced problems by changing the driving light bulbs with Xenon replacements.


FREELANDER DISCOVERY KIA H4 ULTRA XENON HEADLIGHT BULBS
“Blue Vision replicates the HID High Intensity Gas Discharge System fitted as standard to more and more of today's prestige and performance cars. This is because the new and improved design means the bulb burns at 4000K (Kelvin) - no other bulb has this colour temperature, which is the closest to natural daylight. The lamps recreate daylight driving conditions at night therefore contributing to safety and performance. “​


The reason I am asking is that the lights I have currently don’t appear to be bright with they are on dipped, or on full beam

Just I don’t particularly want the expense of having spot lights added.
 
the only prob i have found (from fleabay) is yu need to get the same wattage - if ya dont - ya risk melting the plastic light surround. I have been caught out with offers stating 65W but when they turn up they are 100W. other than that nice bright daylight blue lights - certainly scare the s*** out of low sportscars when yu are behind them - they cant see a thing!
 
just check when they arrive that they are wot they are supposed to be. I fitted them (H4) into my hippoo, GT40 and T220 - mutts nutts. Dont forget later models used H7's
 
I think you'll be disappointed with filament bulbs in xenon gas running the same wattage. Excuse me for appearing patronising if you know all this already, but just incase here goes:

  • The xenon gas in these bulbs does not affect the colour temperature of the light. Xenon is just an inert gas, like halogen and it's job is to not react with the filament.
  • At 55 watts the bulbs will produce no more light than an equivalent 55w bulb.
  • Colour temperature is influenced by how brightly the filament burns and the colour coating on the bulb.
  • If a coating is applied to the bulb this will reduce the effective light output of the bulb by filtering out the warmer colours in the spectrum.
  • Xenon bulbs and gas discharge lights (GDLs, also known as xenons) work in two different ways. GDLs strike a high voltage arc of electricity to create the light, using a similar principle to an arc welder.
So buy a set of high output halogen bulbs, Ring and Philips (amongst many others) do a good value sets with a demonstrable increase in light output.

that told me! - still mine seem brighter and whiter.
 
Wotcha flopster.

They usually are brighter and whiter - than a bog standard bulb. But xenon gas don't make them whiter, it's the blue tint that does, at the expense of absolute light output.

Dunno if that makes any sense:confused:
 
Evenin' Mondo chap.

Good old Fred. He said things a bit funny, but he was a proper chap. Used to see him around Bolton when we lived there 20 years ago. Pulled up at the lights by the station once alongside Fred. I was in the Series 3, he in his lightweight and we exchanged the nod and acknowledgement of fellow Land Rover people.
 
I Fitted Some Halfords Superbrights When They Were On Offer 2 For 1 At 14.99 Theyre Awsome
 
Craddocks sell a pair of Ring 60% better output H4's for £7.99. Got a set in my Defender which replaced a pair of silly bueish white bulbs. Bargain and mucho light.

Won't last as long though as bog std ones, only downside I can see really.
 
I bought a pair of xenon h4's off fleabay with free side bulbs thrown in £6.98 including p&p.

Fitted the bulbs and night time visabilty is much better the light is whiter and does seem to illuminate the road more, at least giving the impression they are brighter, but I'm not convinced that is the case I think its just because the light is a cleaner whiter colour the headlights were bought around 7 months ago and they are still as bright as they were when they were first fitted.:)

The side bulbs were a waste of time after a few days the blue coating on them was burnt a dark brown and the bulbs had to be replaced with led's which are much better.:)
 
dead easy, you stick a fred on here and everybody says yup i'li go, then when you've done all the hard work to sort it out, ever body say oh! i have to paint the garden bench that week.
