I have a set of H4 HIDS on my fiesta, but the bulbs arent very good, not producing that much light, is it possible to put different H4 HID bulbs on the transformer pack thing that comes with it? (electronics rookie)

cheers

 

They're H4's, just had a quick look under the bonnet at the power-transformer-thingy's which say on them

"HID 35-MD-03
V in 9-16v
V norm 13.5
l norm 3.2A
l in max 10A
P out 35W norm
T case -40 - +105degrees c"

then it reads to the side "vout 23kv max"

so if anyone knows wether i can swap these bulbs for brighter ones, or any help at all this would be much appreciated as im an electronics retard.

cheers

 

Something wrong if they don't seem bright mate..
Bulbs last for years..
May be as well just buying a new kit and start again, mine were £25 delivered from eBay.

 

Thats probly part of the problem.. No decent HID kit will cost 25quid.. Good bulbs cost more than that

 

Mine are spot on.
Amazing how cheap stuff is out of China, most of the expensive kits are made there anyway for huge big name companies.
No issues at all with mine. £25 delivered.

 

you can buy bulbs seperate and ballasts seperate as well just go on ebay and search H4 HID bulb and im sure you will find loads!

 

Worth checking your voltage and earth before spending?

 

thats what i thought! i want to make sure im buying the right bulbs...where abouts will it say what voltage etc?

 

Ideally you'll want whatever voltage you've got at your battery. Anyless and there's problems.

 

H4's should have a seperate supply and earth to the control relay, this might be built into the ballast but it depends on the kit. Voltage on the existing wiring shouldn't be an issue so long as there is enough power there to turn the kit on.
Just check the earth and power connections to the control relay, if that fails, bin it and buy new. I'm impressed with my sniper automotive kit, www.in-car-stuff.com I think it was, same as slammedorion above

 

Spooky, I just ordered a set of H4's from there for the Transit Connect

 

Pretty sure next year they will fail mot unless the car has headlamp washers fitted

 

it says "V in 9-16V" on the ballast
"V norm 13.5"
"Vout 23KV max"

pretty sure car battery is 12V

will this restrict which bulbs i can use?

 

You posted up a topic a couple of weeks back asking about getting some, I said don't bother as they are a load of shit. You've now bought some and have posted another topic complaining that they are a load of shit?

Go figure

 

i bought my HID kit and fitted it about 8 months ago...

 

I see the topic was dated back to January, how time flies eh

 

a good set bulbs better job tbh, had few hids an nearly blind people of the road
