Took the new 320d Touring out for its first night drive and my god the headlamps are poor, thought my Passat's were bad! Any recommendation for decent bulb replacements? Ring, maybe? They work well on the MX-5.
OSRAM Nightbreakers are good, and they are a lot brighter than standard bulbs. I'd avoid the Halfords equivalents, as I have found that they burn out quite quickly.
Night breaker+ last longer - some places offer 12 month guarantee. Our XF ate a set in much less than that, but the last headlight bulb (don't known what brand as replaced during service) only lasted 4 months. It's 'blown' 7 headlight bulbs in 28 months!
