I bought my HID (High intensity Dischacge Lights) from ebay for about £50, i fitted them myself very easy to fit. Forget about buying bulbs that are supposed to give you the same effect, over the years i have paid alot of money for so called "whiter light" bulbs, all failed to impress.
I like the visibility that a HID gives off. the lights replace your existing bulbs and you have a small controll box that you fasten behind the light.
Alex's Z4 already has HIDs as std - I think he is just on about changing the OEM HID (probably 4300k) bulbs to a slightly higher temp
What sidelights are on the Z4? 6000k HIDs are very close to the colour of LEDs if you want them to match. Dont forget to get canbus LEDs if you do swap them though, as non canbus ones will mess up the lighting warning system
Correct Stu, it's not that I want to change the colour in particular it's just that they have lost brightness and need replacing anyway so looking for advice on temp.
The Z4 has LED side lights, I bought them a while back, I think it was you that was selling them and told me where I could get them. Seem to match quite well the bulbs that are in there now (4300k I presume). I will probably go for 5000k as has been recommended elsewhere too.
Just a note for TheComputerLab, those HID conversion kits can quite often scatter light all over the show and do a cracking job of dazzling people. What car have you got them in and are they projector lenses?
Im pretty sure your car will have 4300k D2s lamps as standard. As you use them all the time then perhaps they have started to lose their brightness with age as all gas discharge lamps do. You would see an improvement just replacing like for like. Personally I would go for 5000k like all those mercs use as I think they look great although 4300k apparently gives you the most light on the road. I use 6000k lamps and they are very bright but I think they do look slightly chavvy.
Yep, D2S and I think you are right with the age thing, they're quoted as being good for the life of the car and can last 3000 hours, well 3000 hours doing 30mph = 90,000 miles and guess what mileage my car is about 200 miles off
They probably should last the life of the car if you only use them in the dark
Someone else told me the newest Mercs use 5000k so with that in mind I think I will be going for something like this;http://www.hids4u.co.uk/D2S-Upgrade-Bulbs-brilliant-white-high-quality-5000k.html
