Xenon HID lighting

Hi, I have been reading about High intensity discharge lighting conversion kits for bikes. seems for 35 watt input you get a lighting intensity equivalent to 100 watt conventional lighting. there are UK kits in the £70 to £150 pound region, and on eBay from Hong Kong kits for £ 50 including air freight. hiding the ballast pack is one problem, but has anybody tried this form of lighting, and can recommend or otherwise ?

Too good to be true?

Well the hong kong kit is £12.50 including bulb and ballast. I recently had to replace just the ballast on a mercedes car and it cost nearly £200. On the face of it the e-bay deal looks too good to be true but for that price it must be worth a try. From the feedback it looks like they have a lot of satisfied customers. I have ordered the kit and will let you know how it goes.

You got to be careful because there are a lot of fake HID bulbs and kits on the market. The tip off is if they are too cheap or don't have a ballast - a true HID will always have a ballast, and is unlikely to cost much less than $100 (though prices are coming down steadily).

The problem with HIDs, for use on older MCs at least, is that its hard to get a low and high beam out of them, for machines which originally had a single high-low beam bulb. The kits tend to handle this by either using a halogen for the low beam, or some even have a little solenoid that moves the bulb up and down or in and out to approximate a low and high beam. All which would be hard to squeeze in a Miller shell!

If someone ever solves the hi-low problem, these would be terrific lights for older bikes, since a 10 or 20 watt bulb could give a totally adquate beam, and still run off an E3L with power to spare.

I just had a look at these H I D bulbs,didn't know they existed.(Only just fitted a halogen bulb)this site:- www.autobulbsdirect.co.uk/home.php?cat=277 have a motorbike option for half a kit.Looks like a H4 Bixenon bulb would be needed for the dip/main beam as a lot of the kits are supplied for separate main and dip lamps.How you would mount the bulb in an older type reflector could be a problem.

HID's alternative supplier

I was also thinking about fiting a kit a while back, and spoke to a guy called Ian at www.hids4u.co.uk
He was very helpfull, and also supplies a bike specific kit for arround 120 quid.

The thing you have to bare in mind is that the warm up current for the first 20-30 secs is in the region of 8-10 amps, then it drops to a running current of 2-3 amps. Also dont think that going for the highest kelvin number on bulb brightness is best. Take the advise of an expert, as they usually know what their talking about

I couldn't agree more.I looked at both sites, the site I put in the link for said the kits were not road legal and the one that Comet Rider put on says they are.:confused:John

I bought a new car this year and it has this type of lighting. I was amazed when I first drove it at night, on the darkest night it's as though there is broad daylight in front of you.
I hate meeting other cars with this type of lighting though.
My friend refers to my new car as "the one with the Screw the Other Guy headlights"

Bixenon probably means that the low beam is xenon not HID. True dual-beam HIDs are very hard to find, and you're unlikely to find one at that price.

It's Here

The kit from Hong Kong arrived today - 8 days and less than £30.

I have just tried it on the bench and it works very well. Much brighter than a standard halogen.

The initial start up current is around 8 Amps but drops away to 3.6A in about 10 seconds. Dip and main is done by way of a solenoid moving the reflector shield on the bulb and this is very effective. Finding somewhere to hide the ballast box looks like it may be a challenge but I will let you know.

I have a 7" lucas headlamp with the modern glass/reflector from a Volkswagen Golf ( a worthwhile modification on its own). With this HID bulb the dip beam cut off is sharp and clear just like a modern car.

With regards to legality, the main objection on the government website was that fitting an HID lamp invalidated the type aproval for the vehicle. This is not a problem with the Vincent as they are too old to be type approved anyway and do not require 'e' marked lamps.

There can be no problem with the MOT test as the only requirement is that the light be substantially white or yellow and that the dip beam cut off is within limits at the time of test. Whatever you fit must give a better beam pattern than a Miller.

I will post some pictures when it is up & running.
