As far as I can tell they are like LED light bulbs, if they fail you throw them out as they are only about $1-2 each.
OP, I do think it's a bit like the Irish road directions: If you want to go to X, I wouldn't start here if I were you. ;)

The trouble is the damage they might do, when they fail: think fire and smoke.
My advice is for the original poster to return them to the seller, giving flicker as a reason why they're unacceptable and demand a refund. Sellers shouldn't get away with selling crap like this. It's not the buyer's responsibility to fix defective goods.
