I own .hundreds. of lightsets as it is .LOL.
I bought a few things this(well technically last season, mostly common/nothing special stuff. (infact bought a small lightsset today)
For the most part I consider lights as something to buy on clearance after Christmas
Did find a load of yellow/amber incandescent strings which are bloody hard to find otherwise.
I've seen them at Lowes most years.
LOL if you lived in CO I have extras I coulda sold LOL
