I found this video on YouTube, so it does appears that it is possible.

I fancy having a crack at it myself. I suppose that I might as well replace all of the bulbs in one go, rather than having to dismantle the headlights again.

It looks like it's about £20 for all four bulbs on Amazon (two low beam and two high beam), although I can't work out which of the H1/H7 is high beam and which is low beam.

They both seem to be 55W, so are high beam bulbs the same wattage as low beam bulbs?

Hi again.

Thanks again for the help so far.

I've just looked at the headlight again, and I've realised that I'm not entirely clear on what all of the bulbs are called.

The headlight knob on the dashboard has two settings, I think that they are "side lights only" and then "side lights and low beam", and the "high beam" is controlled by the stick to the left of the steering wheel. Are they the correct terms?

If so, it is the low beam bulb which has gone. So, I think that (from what elekie&a/c doctor said), I will need an H7 for the low beam.

I had planned to replace the high beams also, but given that I hardly ever use them, perhaps they are a long way off from needing to be replaced, but maybe I should replace the side lights, which are used at least as much as the low beams.

Does that seem a good idea and, if so, which bulb would I need for the side lights?
