Hi @t8ups, I am a complete noob to lighting but @<tuffty/> recent project has got me interested but I really don't know what lights I have and I want to understand lighting I have an Audi S3 8L with standard lights and have always thought that the light output from both the dipped and full beam is pretty poor I had a look last night at them and can see that the 'dipped beam' is a separate bulb to the full beam - right, that's me done...lol So, do you know if both bulbs are HID as standard? or is the main beam a HID and the dipped beam a normal Halogen bulb? Is the full beam a Xenon HID? Also what do the H# numbers mean when talking about HID/Xenon bulbs, I keep seeing H2 and H7?? and Ds2? or was it D2S?
