I haven't changed the headlights on my Punto since I bought it in 2012. Now with a lot of night time driving I am planning to get some brighter bulbs for the headlight. After going thru a lot of threads at teamfiat, I am a bit confused with what I need to get it changed. Here's what I am looking for and my questions along with it: 1. Planning to change only headlight bulbs and not the fog lamps. Is this advisable? 2. Do I need separate bulbs for low and high beam? 3. I am assuming that H4 bulbs is what will sit on my Punto. Correct? 4. Philips X-treme Vision and OSRAM NB are 2 competitors here. Any other suggestions. Please note, I DO NOT want to upgrade to 100W or HIDs or LEDs or any of those jazzy bulbs. Just want to change the bulbs with same wattage with better/ brighter throw. Hope someone can throw some 'light' on this. Thanks for your help!
