H7 Halogen headlight bulb fittings

Featured Replies

Are these bulbs typically push fit or twist fit like a bayonet?

I've got a blown bulb stuck and I don't want to be one of ****s who drives with with only one lamp tried moving it in most directions and its not budging.

Try screwed in place with no clearance to work and no tools. to bodge it with either. And both my sidelights habe failed atthe same time. Smart enough to carry spare H7s but not W5Ws or the tools to change th3 H7s. Kn0b.

Usually a H7 is held in with a spring clip,. going either side of the prong.

Pretty cr*p that they have used a screw as that's asking for trouble with age.

Like Mark says, H7 lamps are designed to push in and be held with a spring clip - certainly have been on all of my previous cars. Hence the shape of the base, to ensure correct fitment:

As for the sidelight bulbs, they should just push in (and tend to be fimpossible to get out again IME...)

Headlight cluster-out job, is it? How stuck are you - I'm only up the road from you today, and could come 'avec outils' if you're desperate...

BTW, are you trying to get the lamp out of the adaptor in situ, rather than getting the adaptor and lamp out of the cluster together?

I've since done some googling and think I've worked it out, I shall be going out in a bit to give it a third attempt. It is possible to do without taking the light out as I'm sure that page says, I haven't read that one yet but I imagine it describes the same thing, take off the leccy connector, take off the rubber boot, the "clip" is actually hinged not sprung so I shouldn't have to unscrew it. and then the bulb sits in an adaptor. Should be able to complete without special tools. I was stuck at the clip before. Typically the one I need to change in the cold and dark is the more awkward of the two. Unlike the main beam, indicators and parking lights which are simple twist, pull, change bulb, push, twist affairs albeit with not much finger room. The biggest problem I have is that I'm on plant on Weds and I'm mincing about desperately trying not to cut/graze my hands which wasn't helping me.

Fair enough - third time lucky and all that! :)

Just read that link, rofl

This more or less covers it http://www.fixya.com/cars/t892106-replace_front_headlight_bulb

I want to get it done before I set off home as I'm worried the other bulb could blow at any time. 3.5 years old the pair of them.

hopefully you've done it now, but iirc we had problems with the connectors corroding and falling apart on the back of the bulb, i hope this isn't the case for you

No, the clip foxed me still. ITs something like this attahcment isn't it. Tried moving the clip vertically at A but no joy. Some movement but no abracadabra to open it. Going to go out with some pliers in a bit and have another go. Dropped one of the plastic fasteners for the plastic bit in front of the fuse box too.

aha, I managed to take this photo this afternoon

the adaptor contacts were a bit corroded, I hope the bulb is ok. I assume the clip releases on the left and is hinged on the right.

Don't know why it bothers me so much, you see so many cars with only one headlight. But it does.

One end is mounted down, the other end you push each side backwards then sideways.

Do each side and then the thing should hinge open for you to remove the bulb.

Note I said should. These things were much simpler when you had room as per older cars.
