If you are like me - fingers are not as sensitive as they used to be or they are just too big to get into these small areas.
This tool is ideal for inserting or extracting E5 bulbs as used on Model Railway systems, etc.
For extraction just push the end of the tool onto the bulb as far as you can and then turn anticlockwise.
Please note there will be times it will not work due to age, corrosion or other foreign bodies. Try a little WD40 this may help.
For insertion push the new bulb onto the tool up to the metal part, insert the bulb into the holder and turn clockwise, when it's a tight as possible, just pull the tool off the bulb.
