Hia. There is a 2d flourescent square shaped light on my cieling. The bullb has gone and I have bought an identical replacement bulb. However it seems I need a strange tool to open the cover of the light. The screws on either side look exactly like the screw on a meterbox only smaller. Does anyone know where I can get the appropriate tool? Thanks.

This is the tool to open the fitting.


The key usually comes with the light, not sure if you can get one seperately. The good news is that the screws can be undone quite easily with a pair of long nose pliers and a bit of patience ;)

Yes I think that is it. I guess the original key has gotten lost.

I have tried opening it with a pair of long nose plyers but I just can't grip and twist them. I have a feeling that I made one of them tighter by accident by twisting it the wrong way as I don't k now which way is looser and which way is tighter. It moved a little at first.

If you know the name of that type of key then I could maybe search it on google. It's a real pain.

When I use pin nose pliers to take these of I find it easier to lean the pliers to the side when gripping and the moving the whole thing round, not just turning the nose of the pliers. However if the screw is recessed too deep into the fitting this may not be possible.

I believe that you will want to turn it anti-clockwise.
 
If you select the right size nut driver bit, it'll mate with the three points on the screw ;)
 
but as i turn my hand, the top part goes left and the bottom part goes right... am I tightening it of loosening it?
 
Someone always has to spoil it! I trust you aren't equally confused by this concept when you're operating your car's steering wheel! ;) :p
 
no.. clockwise to go right, anti-clockwise to go left.. not a hard concept..
but lefty loosey, righty tighty is flawed as it doesn't say which part has to go which way..
if a spanner is on top of the thing being tightened then it's correct, if it's underneath then it's wrong..

They came with "THORN" fittings,

The Thorn Panther range fittings still use them and some other external fittings, to prevent kids tampering eith them.

Best thing once there out, is to cut slots in the head and then a normal screwdriver can be used, providing they are not required to be tamperproof.

Sometimes a small socket set will loosen them.

With some fittings the screws are optional, but not sure if the key is included in the kit.

For 1 fitting it may be an expensive way to open it.
What area are you based.
 
Are the screws plastic? If they are, heat up a knife on your cooker ring, then use it to cut a line in the screwhead. Let it cool and undo it with a screwdriver.

Not everything is threaded clockwise. The bezel on a fan grille, the bolts on a nearside VW Beetle roadwheel...

what happens if you are in reverse and looking backwards through the mirror? you'd turn right-tighty to go left (y-wefty) :D
 
if you're looking in the mirror, left is still left and right is still right..
if you were facing backwards then it would be oposite, but then again it'd be hard to drive whilst facing backwards..

I suppose, unless you have rotating shoulders or a neck like an Owl.

But when you are reversing, really, you are facing left, looking backwards from the corner of your eye.

So, does that mean to turn left whilst reversing, you have to turn the top of the steering wheel backwards toward the right side of the car?

Lets have a comment from someone who likes reversing left hand drive vehicles.
