Fitting a HID kit

So does anyone know if the £70 kit will work on a 964?

yep providing you get the right bulbs

Ok so as long as I specify the H4 conversion bulbs, it will work on main and dipped beam? so does the £70 kit have twin filament or a shutter system then?

[aceparts_com]

it has a normal bulb for high beam which lasts 5% of the life of the HID = you spend your money and you makes your choices (i'm sounding like henry now!)

The £70 kit on eBay is just a pair of HID bulbs, ballasts & wiring, no shutter or anything like that and if you only buy one kit you'll only be able to do dipped beam. I guess if you want to do both dipped & main beam you could buy two kits and could fit two ballasts at a push but it'd be very tight in the left-hand wing due to all the extra pipework on that side (in a 993). The time for them to light up is negligible, less than half a second I'd say, but not "instant" like a normal halogen bulb.

It's dead simple to fit, you just pull the 2 wires off the back, unclip and remove your existing halogen bulbs, put the HID bulbs in their place using the existing clips, attach the two wires that previously fed your bulb to the thinner wires attached to the ballast and attach the thicker wires from the ballast to the connectors on the back of the HID bulbs. Everything is plug & play, with all connectors being different to each other so you can't get it wrong even if you wanted to! The kit is supplied with brackets and screws for the ballasts or huge double sided sticky pads. I just cleaned up the area where I wanted to attach the ballasts and used the pads to attach them inside the wings and they feel rock solid. The only thing that needs doing that isn't just plugging / sticking things together was drilling a hole in the back of lamp unit using a 23mm hole cutter to get the rubber grommet into that holds the 4 wires from the ballast.

The difference they make is incredible. I had my brother with me in the car last night and his comment was that it was like "driving in daylight"!

Here's a pic taken half way through the job so you can see the difference. (Admittedly it was taken with my phone which was all I had at the time so the quality is a bit shite.)

Did it on my 964 and stuck the ballast boxes on the inner wing under the carpet. Used sticky number-plate tape/pads.

Hi Robmug,
were did you buy yours from ?
cheers Graeme

Sorry - only just spotted the question. Got my HIDs from www.hids4u.co.uk

[wildoliver]

Right, so is the halogen bulb that only last 5% of the time of the hid replacable? or is it part of the HID bulb?

I can get my head around the idea of fitting 2 kits, but how precisely would you set one bulb up for dipped and another for main beam? not talking about wiring talking about how it mounts so doesn't blind traffic + will pass an mot when on dip.

I'm not sure of the set up on a 964 but on a 993 there are two separate H1 halogen bulbs, one for dipped that remains on all time provided your lights are switched on, and another for high beam that can be turned on or off as and when required or "flashed". If a 964 also uses a similar set up with 2 bulbs then you can replace the dipped beam with HID bulbs while leaving the main beam bulbs as standard halogens. So given that they're just a bog standard bulb that do blow from time to time then you can just replace it as normal. HID bulbs should last many thousands of hours as opposed to several hundered for the halogen, hence the "only lasting 5%". It is completely independent of the HID kit.

Remove the old bulbs, put the HIDs in their place. They aren't free to rotate or move up & down as the base of the HID bulb is the same shape & size as the base of the halogen so there shouldn't be any need for an adjustment. Probably best get them checked though, just to be on the safe side.

[wildoliver]

Right the problem on a 964 or earlier is they use a single H4 per light unit.

This means that I really need one bulb (HID) that does main and dipped beam as that is what is fitted at the moment, the H4 has twin filaments So I either need a twin filament HID (do they exist?) or a shuttered bulb? Yes is this right?

Need help!

[verysideways]

Don't bother - get an H4 kit for the dipped beam and leave the standard bulb in the high beam - that way it'll work great when you flash someone, it'll work fine at night when you flick to high beams (which won't be often) and you'll have HID's for dipped beam (which almost negates the need for high beam at all).

Without wishing to sound like a promotional guru you need a SHUTTERED hid kit, alternaitvely you can buy the cheapo option which is a HID bulb for the dip beam and sealed to the same base is a focused halogen bulb for the high beam

[robmug]

Yes, you can get a kit for the 964 that is main AND dip. That's the kit I have from www.hids4u.co.uk. There's a solenoid that pulls the filament into the correct position for the main beam.

Is a shuttered kit harder to fit? What's the cost for a shuttered kit for a 996 C4S?

Thanks
