I bought Philips White Vision Ultra replacement bulbs (for headlights and side lights) for my Ford Fusion 2006, from Euro Car Parts. These tend more towards the light blue part of the spectrum than yellow and are a straight swap, giving greater beam reach and better visibility.

Haven't fitted these yet because I read somewhere that bulbs that are not standard replacements may not meet the Road Traffic Act and Insurance company expectations, even though they would increase night visibility and safety.

Would appreciate your views on this matter - fit or don't fit?
