Hid Conversion

[Rob-Halifax]

Anyone done this on a Mk1 GS?

I've been playing with a conversion kit for a couple of weeks now, I have the right type of kit with the right bulbs to do the conversion, it's literally a case of unclipping the normal bulb and plugging in the connector for the new one or so I thought.

I can get these bulbs to light up on the desk using a 12V power sully and crocodile clips, when I take it and connect it to the plug that fits onto the bulb, it won't light up.

It says on the bulb case that it's a 12V 51W hologen bulb, the ballast needs a 12V power supply to make it light up. WHY THE *&%^"!! CAN'T IT JUST LIGHT UP WHEN I PLUG IT INTO THE CAR'S PROPER PLUG???? AAAAARRRRHHH!

Would anyone that already done this conversion know why I am having this problem? I'm completely at a loss

I take it you are plugging the ballast into the cars existing 3 pin bulb socket?

If so the pin outs on a Lexus are wrong for the ballast and the connections need to be moved around.

If you have a digital multimeter it is fairly easy to explain.

No Steve, on the GS th bulb only has 2 pins, you're going to tell me the the pos is neg and visa verse?

Oh, and yes, the ballast is simply fitting between the cars bulb and socket.

Of course,sorry mine is the LS so has the 3 pin connector which had to have the pins moved around.

The +12 volt supply should be present all the time on the bulb connector as Lexus generally take the negative feed to the headlight switch and from there to ground thus completing the circuit.

Have you confirmed which wire is positive on the bulb connector?

[Rob-Halifax]

Erm, damn you teccie folk lol

Not sure which is which to be fair, would they have different coloured wires?

Here's a question the Steve, what will happen if I switch the wires round and then plug it in again, will it just not work or will something go bang, pop or wheeee! ?

Scratch that, it had to be something as simple as the pos and neg the wrong way round.

A quick snip and solder the red wire to the black etc etc, sorted.

Looks wrong but it works, silly Lexus designers.
