Just replaced my halogen flashers with LED, and changed the flasher relay, works great except now the flashers don't light when locking and unlocking. Any suggestions?

Simply put you didn't buy the right flasher that supports the lock/unlock confirmation. Currently only v-leds.com's flasher supports this but they have been out of stock since Nov. Flashers from any other website do not support the confirmation flash.
