Without doubt the thunder grey and blue looks brilliant mate, the 2 together would make a nice photo
Yes you pretty much got it, the bulb in one side does provide enough resistance.
I did go down the resistor route first, one in each side but they got so so hot, and I was not confident that I could desperse the heat, equally I could not find a place or should I say anywhere practical on the RR to fit the the resitor that would not cause damage.(they were already enclosed in a heat sink block) but still they got seriously hot.
I am not an electrician so please forgive my ignorance and lack of techinical knowledge, you completely lost me on the ohms, but one 12v (3W) certainly provides enough resistance to fool the system, and it was as simple to do as fit an extra bulb holder to the existing plug.
This 3w bulb does not get anywhere near as hot as the resistors (I previously tried) the headlamp refractor is designed to take bulb heat so by positioning the bulb on this (there is a gap were the sidelight entry hole is and the refractor just right for this) when installed removes the risk of heat damage to plastics and wiring, after 380 miles of use since the mod there is no sign of damage not even dis'colourment.
Thanks
