thought i would do a run through on how to repair these.
step 1 is to prise the white backing peice away form the black plastic front piece, i know its hard but it does come apart.
some bits of the white part may break away but it doesnt really matter as long as most of its still there because if you didn't fix the bulb it would end up in the bin anyway wouldn't it
you need to get this bulb AND the holder its in out of the white plastic, it requires a little bit of heat, i havent tried boiling water yet but a hairdryer works.
heat up the plastic and push the terminals hard from behind and it will pop out.
step 3 once out you need to pull the terminals out which i found came out fairly easy with a bit of heat and a pair of pliers.
then smash the bulb and pull all of it out of the holder with pliers.
then you can insert the new bulb with the wires coming out of the origenal holes, then push the connectors back into place (tech tip before putting the connectors back put a dap of solder on the bit where the wires are to be soldered to.) so you can solder the bulb wires to them, dont forget to test the bulb before assembling and for LEDs you have the correct polarity or you will be doing the job again.
step 4 reassemble the bulb back into the white plastic housing then use some glue (i used this stuff http://www.hobbycraft.co.uk/loctite-all ... 04762-1000
) to glue the white backing piece back to the black plastic piece.
this is what it looks like, its the closest ive found to the origenal spec without it being too bright and in your face.
