Hi, why don't you just fit LED bulb with built in resistors to your existing fittings, around £24, much cheaper option.I'd go for it, even if it's just to give yourself that extra chance of being spotted by the idiots that don't pay attention when entering a junction or changing lanes... Sigh
I looked in here http://www.volvocars.com/uk/all-cars-MY13/volvo-v40/specifications/pages/accessories.aspx but couldn't find them. Was I looking in the wrong place?I believe they are. LEDs are available as an accessory on Volvo's website.
That's exactly what you can find there:
LED Day Running Lights £345 (Fully Fitted)
A low-placed light that gives the car a modern look. LED lamps emit a strong white light that makes the car easier to detect and improves traffic safety.
£345 - Price includes all parts, labour and VAT.
