Those light bars are a sugihara or tsumura, husky gets supplied by both, the one you've got here is a sugi. Probably easier to find and cheaper to just buy a sugi or tsu light bar.
Even on the 592 it balances nose heavy with the standard 24" bar.. $128 for a 24" light bar.. but that's an expensive half pound if you already have the regular X-Tough bar like i do.. Just weighed it and that saw with the regular 24" Husqvarna bar and full tanks of fuel and oil weighs 22.2lbs.. so i half pound isnt that much, I don't know maybe someday I'll get the light.. just wish it was more than that
Don’t know if Husky does this, but each of the saws I have purchased from Stihl shops, I have only paid about $50 more for the light bar with saw purchase. 28” light purchased separately cost me $152 and 25” cost me $122. ⛓🪚👍👏 Rick
