I bought 2 sets of HID's from a seller on here a while back, and one of the ballasts packed up just over a year after purchase, so I wil not be buying from them again. I bought another ballast from China to match the original, but now another ballast (on the other car) has gone and I need another.

The ballasts I have are the big old chunky ones that take a large starting current and are slow to start up.

I've seen mention of "slim" and "digital" but there's also A/C and D/C

The HID kits I have are the ones where no relays are needed, and you just cut a little hole in the rubber cap at the rear to pass the cables through. Although the ballasts have been changing over the years, how about the bulbs? I'm noticing that some are now turning slightly yellow, should I replace them?

Given the low cost that some of these HID kits have fallen to, is it worth getting just new ballasts (I assume connectors will still be the same?)

Can all new slim/digital ballasts be use with older bulbs?

Is it the ballast that datermines how quickly the bulb gets to full brightness, or is it the bulb?

What's with A/C vs D/C?

Note: I won't need any CAN-bus stuff, my cars are too old for that!

For the price of the kits I'd just buy a new kit. No problems with connections/differing bulb colour.

Can't help with which kit to buy. Always had the large packs, but haven't been bothered by the bulb warming up.

here you go , they are in the uk so should only take a couple of days to get to you , slim ballasts and only £15 delivered -

Yep, I am with szkom, get a complete kit and for more light go for 55w and 4300k light temp

Only £15 that is cheap! I had a failutre on my Stilo and purchased a complete kit, so on strip out I knew I'd have what I neeeded (bulb or transformer)to hand.. Personnaly I'd go with the 6000k to have the white colour, above or below is tinted yellow or blue

Are these Hids any good at this price?
Seem too good to be true

I need H7's for non-Coupe cars, they seem more expensive for some reason, but it's all relative I guess, the first set I fitted to the Coupe some 10 years ago or so with separate relays and all (not plug n play like now) cost over £200 in a group buy from the US...

So are all early/old ballasts A/C and only the cheap as chips new ones D/C? Or is A/C just the latest innovation? Do all the A/C ones come with a separate inverter (easy to spot extra little box 'twixt ballast and bilb) ordo some have the inverter inside the ballast casing?

How much difference do they make? How easy to fit?

As a new owner I'm already a bit bored of the pitful lights

Those examples above are being sent from Shanghai, so they could be picked up for duty and VAT by HMRC when they come into the country.

They will take several days to get here, more if they get picked up by customs.

They are in the UK Pete if you check the shipping for the item.

MiniMan64 , yes hids make a big difference over the standard coupe lights . Easy to fit and should only take you 30mins to do , they are just plug and play units , I think there is a how too guide on installing them .

Great link nismo, just ordered a set. Top man! That's cheaper than a decent set of standard lamps

So how comes there are AC/DC variants? Does this matter?Which is best if so?
