Board Thread:Warhammer 40k Modeling and Painting/@comment-6078851-20130309150331

i'm almost finished painting mr thraka and i've only just noticed that i have no idea what the 2 cylindrical things are which sit at the very top of his armour.

now i can paint them in the colours they are generally shown to be painted but it still doesn't clue me in as to what they are.

i used to think they were mini-flamers but there's no such thing as part of his wargear - they're not weapons at all as far as i can tell. i then thought they might be torch's or spotlights but the colours they're generally painted doesn't make them look like such.

painting them isn't really a problem but not knowing what they are is bugging me, can anyone illuminate me as to their purpose or function?
