need a bit of help with this one,I have just changed the boot lights to led bulbs no problems,changed the footwell lights to led's no problems then I changed the top center light to led again no problem but when i change the two map lights to led's they will not work have tried several types of led and put them in both ways but they will not light up put back the original glass 501's and the map lights work ,This has me rather puzzled.  

Hi Rob, 

It has me puzzled a bit too.  I wonder if LED lights are suitable for the map lights?

Regards, 
Peter.

Have just tried another type of led in the map lights and still nothing I guess i am unable to use them,such a shame as the other led's all work and look great.

not one to give up i have tried another type of led bulb in the map light's and they work . I have checked these against some of the other led's that did not work and there is a slight difference in the size where it pushes in and the holder has very thin contacts so the bulb has to fit just right or it wont work.very happy now.
