Single Bulb to Dual Bulb

I suspect the wiring it going to be the lesser of your problems. For the wiring I suggest you start with a shop manual which will show you want you now have in the wiring diagram section and then try to find the closest thing that has dual lamps and see how they are wired.

Are you getting some sort of kit? If so I would expect it to address the electrical issue. If not how are you going to attach those new lights. Duct Tape?

i'm asuming that it is this shape golf and these are the headlights you are talking about

if so, as far as i'm aware they are a direct swap, and have the same wiring connector on them

Andy,

One problem you will have when changing from a single H4 type bulb to

2x bulbs is that with the single bulb when driving on dipped beam only one filament in each bulb is on; when you change to main beam the dip beam filament switches off and the main beam one comes on.

With seperate bulbs, you need both bulbs to be lit (i.e. the dipped beam and main beam circuits) when main beam is on.

This was the problem I came across recently when upgrading to xenon lights.

A simple way to work around this is to connect the headlight power supply wire from the rotary light switch directly to the dip beam wire from the column switch (normally this supplies the 'input' side of the column switch) so that the dip beams are constantly on when the headlights are on. The column switch now only controls the main beams. The flash facility will work as normal without any modification needed.

You need to join the wires between the column switch and the fusebox as they seperate to the left and right hand fuses in the fusebox. Also make sure you join the wires, do not cut the circuits as you still need a supply to the column switch for the main beam part of the system.

Hope this makes sense, if not drop me a line.

Not necessarily. Some cars are wired like that and some are not.

Another solution is found here:

It's not so much the headlamp switch, but the jumper that comes with it. If you don't already have this switch you might want to look into it anyway because it gives you controls for front and rear fogs if you decide to add those later.

it really depends on if this is a euro-spec or a US/Canadian spec Golf. The US/Canadian lamps had the connectors at each bulb whereas the Euro ones have one connector on the outside of the lamp and all the wiring to each bulb was taken care of inside the lamp shell between the back of the lamp and the back of the reflectors themselves. The Euro one would be a direct swap but the US/Canadian would require minor rewiring.

Also if it's a US car, you might want to consider this swap...to dual-bulb Euro units:

That same site shows the dual-bulb US units as $120/side (so $240 total) and these Euro units are $325. So for just $85 more you get the superior Euro-spec lamp units anyway. Looks like it's plug-n-play as a kit too except for minor modification to the radiator support (the Euro and US cars had a difference here that affected the lamp mounting).

Maybe not, but VWs are.

what i'm getting at is it's not any type of requirement law-wise in the US to have to keep the lows on with the highs on a quad-lamp car so you don't

*need* to modify the wiring to have them stay on, as someone indicated.

I understand, but if the dips go out, you lose the light immediatley in front of the car and are only using a longer narrower beam so illumination is impaired. Although it may not be law, I think it is necessary from a safety point of view.

depends. if I need to see long-range, having a lot of light close in front of the car to me is actually somewhat distracting. if I need to see 800 feet down the road with high beams on, that's where my eyes are focused anyway and I really don't need a lot of light 75 feet in front of my bumper.
