I doubt they are gonna be 'plug and play' - especially if you tap into the sidelamp circuit. You need to carefully calculate current draw, and solder in series an appropriate resistor - otherwise you will end up with constant bulb out warnings on the instrument cluster.
cheers mate ,
an electrician said that the current draw should be fine though as LED's as small as 12v wouldnt harm the circuit as the are not one-way wiring.
But he missed a crucial point!

Yes, the actual current draw won't harm the actual circuit - but this isn't the issue. The real issue with the Golf (which your 'electrician' seems to have completely ignored

) is the simple but well-known fact that the Golf uses an autonomous electronic 'check' system. This works on stuff like front brake pads, but also every single compulsory bulb on the car - including side lights. And it carries out these 'checks' even if you havn't actually turned on the said light. And this is why I said it needs an additional resistor soldering into the circuit if you want to use LEDs - because as ANY competent electrician should know - LEDs draw much less current compared to a conventional tungsten filament bulb. And if he was worth his salt, he should be able to calculate exactly what rating of resisitor is required. The simple fact he failed on both counts makes me strongly consider he isn't actually an 'electrician' at all.
do you have any advice on how i should go about this ?
Sorry, no. Electrikery isn't my area.
