ok so i bought a pair of white side light bulbs online

they came and i went to go fit

there is no wiring going to my sidelight bulbs

it seems they are unplugged and my main bulb has a double filament

can some one shed some light on what may be going on

The headlight bulb is a H4, halfords is you best bet for bulbs mate I had the same issue and they sorted all the bulbs out but I got a mate to trace back the wiring! They sell the side light holder on heritage for a couple quid if they may be broke?

If you look at the back of your lights there is the main elctrical plug going to the main bulb, 3 wires going to it, there should also be a hole at about 5 o'clock with another a plug and wire going to it.
Looks like this

Do your parking lights work? Put the indicator on left turn without the key or ignition on you should have both the front and rear light on but only on the left side, or right indicator = right side.

I would not use Halfords unless you need something for your bike, they are so expensive…
Euro car parts etc so much cheaper for bulbs.

the main bulbs are double filament yes but this is for dipped and main beam not sidelights.

the sidelights are separate and use the mini ba9 type bulbs, look closely at the outer light you should see a small hole near the bottom for the sidelight bulb holders. sidelight wire colours are grey/black and brown one one side and grey/red and brown on the other.

the reason it may seem like the sidelights are working without the bulbs may be that you have a later mk1 with the dimdip resistor fitted, which brings the dipped beam on dim with the sides. if this is so the 'sidelightss' will always look yellow no matter what H4 bulbs you fit as they will be runnign on reduced voltage.to fix this you need to remove the dimdip resistor and fit white sidelight bulbs. I found that all the bulbs I tried were yellow so I went for some heavy duty automotive LED bulbs that sorted it.

the dimdip resistor on a mk1 is on the passenger side i believe near the scuttle, look for a ceramic coil about the size of a packet of polos with a yellow wire out of each end, trace the wires back to the 2 pin plug and disconnect it.

you can leave it if you like, but as I say when you have sidelights on the dipped beams will also be on dim and will shine a yellow light rather than the white you are after.

its not required by law or mot so its fine to bin it, i always recommend to do so as the wires can short out and if this happens your lighting loom will catch fire! its worse problem on mk2 golfs due to the wiring runnign over a lip of metal on the chassis leg that can rub thru the wires

ok so all it does is put the headlights on dipped beam when the sidelights are active?

so if i un plug it , plug the sidelights in ill be non the wiser just brighter sidelights ?

thanks

yeah all it does is run reduced voltage thru the dipped beam filaments, so not on full just slightly about as brigt as a pair of decent sidelight bulbs or maybe a little bit more.  since the H4 bulb isnt getting full voltage its only going to be able to put out yellow light really no matter what bulb you fit, though i guess the blue tinty ones might be a bit bluey?

once the resistor is unplugged all you'll see is sidelights when the sidelights are on :)
