Thanks..
Yes, I remember that the dipped beam is H7. I never swore so much in my whole life, changing the driver's side (right) one..

I tried to do it from above but once I got the bulb in, the spring clip fell out.. and after more swearing, I eventually could not get the back cover back on until I removed the inner wheel arch liner and did it from behind....
Then a few days later, the passenger side went....

but that was easier - "just" a battery out job. Luckily/touch wood they've been fine since.
Sooner or later I want to swap the headlamps, since mine are grimy inside the lens cover... but I suspect this is going to be a bumper-off job (i.e. for the summer).
Meanwhile.. I'll get some H1's in yellow and give the foggies a boost.
