Heater control bulb

[mk2man1]

Hi all just changed the bulb and the centre dial is bright green a normal but two outer ones are hardly lighting up.
The bulb was 2.3 watts is that bright enough or did i get the wrong bulb.

Hi mate, yes you got the wrong bulb.... standard is 12V 1.2W not 2.3/2.4. So could we be the reason for the middle lighting up like a christmas tree and comparatively little on the outer ones.

The only other reason would be that you haven't replaced the "spider" properly....
