How to remove and replace the dipper headlight bulb?

[imawheel]

I feel like this should be a really easy thing, but the connection for the dipper headlight bulb on my car is nothing like any of the videos I've seen and I can't figure it out.

I've attached some photos which will probably be better than any description I make.

I found this ebay link to the bulb holder and it looks like the entire black connection and metal case should all come off somehow, but I've been trying for ages and don't want to do something that ends up breaking it. Any ideas?

Also, it says I need an H7 (477 / 499) bulb. I have an H7 (477) bulb, but it looks a bit bigger than the one that's already in there. Do they come in different sizes and do you know if I'll be ok to use it, or should I just give it a go?

Thanks so much!

the bulb is separate to the base part.

it does come out but may need a bit of pulling to remove it.

i had the same problem changing a bulb on my sons car.

the bulb didnt want to come out of the holder but i think that may have been because it was the original bulb from the factory.

you may need to put a small blade or screwdriver between the base of the bulb and the metal clip and ease it out that way.

This a standard H7 bulb in the pictures, the bulb has 2 connectors at the base, all you need to do is pull the bulb from the connection in the lamp unit.10 minutes max
Oh and its dipped beam not dipper fyi

Thanks for the replies! I got it out with the help of someone else - by wedging two screwdrivers under the base, one either side and getting it out that way. Neither of us could budge it otherwise!

there are videos showing the change of the bulb.
