what kind of LED lights & resistor do i need ? voltage, ohms ? where can i buy them ?

do i need to tinker with VAG COM too ?

help pls.

cheers

Sorry, but what is the difference between side light LED and DRL LED ? :oops:

just to check whether i got it right...

if i were to go for the side light LED (501/194/T10 New Mini Light Tower 15 Leds Xenon White), then i need the HS50 Al house wirewound resistor,24R 50W resistor?

and same goes with the DRL LED

DRL LED (V-LEDS HID WHITE 60 M-SMT PARKING BACK-UP LIGHT BULBS 1156) with HS25 Al house wirewound resistor,68R 25W resistor?

is that right?

thanx :wink:

No it's the other way around; DRL's use the 50W resistor & sidelights use 25W resistor. Be warned though, unless you've got very small hands they're a bitch to get to properly!

The search button is your friend :) There is an older thread about this arround here, just search drl led . A bit of advice, don`t put the resistor on the back or inside of the headlight cap, it will melt right through it. Just put it on the back of the aluminium (or is it steel? ) piece that holds your hood and the upper intake piece so it has some cooling and it doesn`t melt .

The 50W resistor will sit inside the cap without melting as the actually resistance of the lED DRL is much lower than the resistor value so the resistor itself runs cool enough. It it were a 25W then you would run into trouble which are the ones that have reportedly metled through the access caps.
