Hi there,

I purchased a 2009 Ford Focus Titanium 2.0 tdci yesterday and I am very pleased with it. I went for a drive at night at thought that the Bi-Xenons were very underwhelming as I had especially looked for a car fitted with them. I assumed that the bulbs were getting old but after reading the user manual they are only listed as 35W bulbs.

My question is can I upgrade the bulbs to 55W ones? I have the headlight washers and auto-leveling so cannot see any reason why I couldn't. Would I need to replace the ballasts?

Thanks

James
