The proper tool for the job

small fingers & think yourself lucky your's is an easy bulb to replace !!! people come into us & say "can you just replace my bulb" those day are gone, we had a Smart Car in the other day, you have to take the whole front of the car off, take the headlamp out then replace the bulb ! that's progress for you.

Not the same problem, but I have come across awkward placed spring clips on my car. I tackle them by making a small hook on a wire, e.g. from a cleaner's coat hanger. Then I can catch the spring clip by the hook and pull it in place.

What about some circlip pliers?

most headlight bulbs are held in with a spring that is hinged to the back of the light, there isn't a tool for it, nor room to use one. It is usually trivial to get it to undo, but hard work to do up (sometimes) I find it is best to establish, without the bulb in the way, exactly which direction and why, you need to push the clip, it is then much easier to reassemble.

The only tool that does come in handy is a pair of long nose 45 degree angle pliers with long handles.
