This might be a bit out of date reply but I was in the same position a few months ago as I also when thru the whole motion of which is best.I must have 8 sets of bulbs in my shed.I did all the research and opinions of loads of people.I tried OSRAM Nightbreakers to PHILIPS Extreme and loads of suggested brands.They were all very disappointing and similar.I fitted the RING 120+ to my wife's 2003 Clio a year ago and the light seemed so much better than my 2006 c class.So I decided to try the same in my car and after spending a fortune on bulbs as they all average between £15 - £20 per set,the RING bulbs are far better than any of the others I have tried.Give them a try next time as I will only use the RING in the future.
