Unscrew and remove the two M3 nuts and washers holding the bulb assembly to the cover pillars. Keep in a safe
accessible location.
Lift the bulb assembly away from the support pillars, thus exposing the filament bulb. Remove the old bulb by care-
fully pushing it down in the holder while turning it anti-clockwise. The replacement bulb can now be fitted. Care
must be taken to ensure that the replacement bulb is the same wattage and fitting type (Ba15d) as the original.
Replace the bulb assembly onto the support pillars and secure using the two off M3 nuts and washers. Ensure the
retaining strap is fitted to one of the electronics assembly mounting pillars during re-assembly.
Carefully replace the cover assembly back onto the base, avoiding damage to the mating surfaces. Replace
the 6 off M5 screws (4.0mm A/F hexagon key) into the holes in the cover assembly and tighten evenly. Ensure
the O-ring is seated correctly on the cover during re-assembly. Ensure the required maximum gap of 0.2mm is
maintained between the cover and the base once assembled
