Hi all as the title suggests.....

Car has been parked up for 3 weeks unused as I work away.....

To my surprise she started fine so I knew I had to be punished for something else instead.....

So on my way home about 20 miles into the journey I get the message ‘check dipped beam’ or something similar.
On closer inspection my drivers side headlight is out.

Can someone please tell me which bulb I require without removing my headlight as it seems I’m at a weird inbetween years age?
D1S or possibly D2S?
