hi, i work in a car service and repair garage and due to my persuasion, the boss has lately started stocking bike stuff(oils, batterys, bulbs etc) in the parts shop, i have noticed some blue xenon headlight bulbs that will fit my zzr400, these are emarked and it says on the packet that they are 30% brighter than standard and are legal in most countries, what i want to know is are they actually legal and will i get pulled for them, thanks alot, adam

Hi

Depends on how blue they are.

Proper HID kits for aftermarket use are not legal.

All the best

Kinda off topic but do you know why?

They are legal for cars so why not for bikes?

Faraz,

They're not legal for cars either UNLESS it is a Factory-Fitted piece of equipment whereby the lenses have been designed to facilitate the different beam pattern caused by a discharge beam as opposed to your incandescent (normal fillament) type bulbs.

So chavs who retrofit HID's into their standard headlight clusters will invariably create a dazzling beam for oncoming road users. The same is applicable to bikes.

IIRC, you need to have a self-cleaning headlight if your vehicle is fitted with HID's and must have self levelling suspension.

Nevertheless, I've had them on my last 2 bikes and the difference is like night and day. I've had the beam tested at the MOT centre and passed. Not had anybody flash me so I can only take that as a positive.

Technically they are illegal... but so are race cans and small plates... except this one is a potential safety aid, especially in winter Wink

To the OP,

Blue xenon ones are "xenon-look" only and will actually emit less light than your stock light bulbs. The colour temperature of a bulb is inversely proportional to its luminosity. I believe standard light bulbs have a colour temperature of about 3000 Kelvin which gives a yellow light. The further towards 12000 K (bluer hues) you go, the less light you are emitting onto the road.

If you want plasma cannon type visibility for night/winter use, you'll be looking at the HIGH INTENSITY DISCHARGE (HID) kits. My recommendation is a 4300 K colour temperature which is like diamond white whereas 6000 K is more of a cool-blueish daytime white if you want the most intense light.

Too blue and you'll be impersonating plod... and gets speeding bikers paranoid if you're followed by one lol

These arent xenon lookalikes, it says that they something about xenon gas inside them and im sure they sed something about 4300k also they are from germany and are supposed to be similar to the ones fitted to the new bmw's etc, the picture on the packet shows a very very light blue more like diamond white as you sed so i think these me the ones you are recomending, but does anyone think im likely to get pulled off pc plod for these as i dont fancy taking my light bulbs out everyday to show them theyre emarked also on that note how often do you guys get pulled for race cans, small plates and tinted visors

tinted visors are almost no trouble unless you get pulled for a few things and get a pain the ass cop which will pull you for everything s/he can

small plates are 50/50 depends on how tight the cops are in your area some people have been pulled like once in 5 years of having one and some been pulled a few times

race cans depends on how loud it is you might not get a pulled on or not, i know i dragged it out abit but hope it helps Thumbs Up Karma

If you want some decent lights look into a set of osram night breakers or philips extremes.

The philips are pretty much the brightest you can get legaly without going the HID route. There was a test done on them a while back in a magazine ill dig it out.and post it up.

You can be like a midnight star, in the case of my 929 which has a huge reflector/lens surface area at the front. I'm running H7 HID 4300K low beams and Philips Vision Xtreme High Beams! I won't go ANYWHERE without the combo. The low beam has high enough intensity to mark out small objects on the road such as wildlife LONG before they would be able to trouble me. The high beams give sufficient range to let me know which way the road is turning in about 1km... A dark A40 is a good way to test my theory.

Anyway, for comparisons of HID's with Philips Xtreme Vision on the ZX6R and 929 Blade.

It's not a good control test since I used my camera for the HID shots and my mobile for the Xtreme Visions. The lens and optics on the phone camera make it appear brighter than it really is

Far beam pattern.

In any case, your ZZR will probably use a dual filament bulb in which case you'd require a H4 bulb. These, in my experience are no where near as good as the single filament H7's if they have HID conversions. My advise is to go with the Xtremem visions.

Safety aid for who exactly. The other drivers you dazzle or for you where the focus point for the lights is closer to the bike giving you less beam reach?

Titz pretty much covered it.

Aftermarket HID kits are not legal for bikes or for cars.

Both will cause problems as HID lights are massively brighter. Headlights are limited to 60W, which doesn't really relate to how bright they are. Trouble with bikes is that if you put a pillion on the back the beam will get a lot higher and with HID lights dazzle people.

With cars I suspect one problem is that many of those fitting HID kits are also the ones lowering their cars, and they probably land up lowered by more at the back than the front, hence again the lights being aimed too high.

There is also the problem that HID "bulbs" take a while to warm up, hence you cannot switch easily from a dip to a main beam bulb. You either need to keep one on full time with the other coming on when required, or some HID kits use a mechanical movement to switch the single HID bulb from a dip to main beam position.

Lastly the exact position of the bulb element in a headlight makes a large difference to the spread of the beam (mm make a big difference). Think many HID "bulbs" have the light emitting element in quite a different position to the equivalent bulb.

All the best

Keith

What I was trying to get at was that the MOT man fettled with the beam to get the beam pattern within the acceptable tolerances of the MOT test. The beam does have extended reach compared to the standard H7 Xtreme vision. Beam does dip down and left with minimal bleed.

I'd be more wary of 4x4's screaming in the opposite direction who have HID's fitted as standard as opposed to a single bike fitted with a HID kit.

In any case, any sort of dazzle, highly intense light source WILL cause target fixation from oncoming cars, HID or No HID.

Unless we somehow develop nocturnal senses of navigation, I can't see any other way to improve your visibility at night.

theres nothing worse than cars that have them as standard just blind you to hell up close

I had 8000k ones in my saxo long ago, they were very blue but didn't ever attract any attention and went through an MOT.

They shouldn't blind you, but there do seem to be a fair few that are badly setup. At least those with them standard will have self leveling suspension to stop the contents of the boot causing the lights to point up and dazzle everyone.

As to the MOT, the test is limited so possible to get one through (just like a race can).

All the best

Keith
