If it helps anyone to knoe I replaced the headlight bulbs (all 4 for full and dipped) by Philips X-treme Vision +130%H1 which I bought on line from
www.powerbulbs.com. I find them so much better against the glare from modern cars with their led lights. My car is V90 1997. Powerbulbs web site has the facility to enable one to get the correct bulb/s for the car model.
