LED candle help

Hi folks! This site is so inspiring! I'm looking to hack a battery powered holiday LED window "candle." The missus likes it because it has a timer to shut off automatically after 6 hours; however, we don't like the way the "flicker" looks. We'd much rather bypass the flicker, but the timer and flicker are all on the same sealed bit of circuit. So, my question: is there an easy way to put a tiny (maybe 3/8") 6-hour timer on an LED? Thank you in advance! --Kiribub
